JUNE 1972 OAK RIDGE NATIONAL LABORATORY Oak Ridge, Tennessee 37830 operated by UNION CARBIDE CORPORATION for the U.S. ATOMIC ENERGY COMMISSION DISTRIBUTION OF THIS DOCtiMEHT IS WUJMTTEp The Research Materials Information Center was established in 1963, as part of the Research Materials Program of the ORNL Solid State Division, to provide information on the availability, preparation, and properties of ultrapure inorganic research materials. The ability of RMIC to answer inquiries depends completely on the flow of current information to the Center. Reprints (or preprints, preferabfy) and completed data sheets should be sent to the Center by all working in materials science and particularly by those producing specimens they are willing to sell, lend, or donate to other researchers. Further information and blank data sheets (which should be used both to announce and inquire about materials) are available from the Center on request by mail or telephone. ALL INQUIRIES, PREPRINTS, AND REPRINTS SHOULD BE ADDRESSED TO: T. F. Connolly Research Materials Information Center Oak Ridge National Laboratory P. O. Box X Oak Ridge, Tennessee 37830 Telephone: (615) 483-8611, Ext. 3-1287 COMPILATION OF CRYSTAL GROWERS AND CRYSTAL GROWTH PROJECTS This compilation lists all those who returned questionnaires distributed Internationally by the Research Materials Information Center (most of them in the last half of 1971). Addresses were taken from the RMIC mailing list, and questionnaires were also sent to those — not on the mailing list — making inquiries to the Center during this period. The compilation includes, in addition to those growing crystals, preparers of starting materials for crystal growth and some preparing ultrapure noncrystalline inorganic research specimens. Commercial suppliers — not always producers — are also included and are indicated by an asterisk after the entry number. The format of the entries is self-explanatory except perhaps for the sections introduced by Roman numerals. These represent the answers to the following questions: I. What is your major interest in research materials [preparation of starting materials, crystal growth, characterization, physical properties research (if the last is included, what properties are examined?)] II. What specific techniques and apparatus are used in your program (Czochralski, mass spectrometry, optical)? III. What specific crystals or other materials are prepared or grown? IV. What is the purpose of the crystal growth or intended use of the crystals (e.g., ferroelectric or electro:optic materials, structure or magnetic studies, study of crystal growth methods)? The listing is followed by separate indexes on: specific materials (alphabetical by chemical formula); general classes, such as ferrites, garnets, group III-V; and the intended use of the material (semiconductor, ferroelectric, electro-optic, etc.). Indexes by growth methods and methods of characterization were considered but rejected (after review of the listings) as simply repetitive. * * * * I am very grateful to Betty Edwards who is responsible for the painstaking magnetic-tape typewriter composition and for the copy-editing and correction of often semi-legible material. * * * * Because a publication of this sort will lead to many inquiries to those listed, it seems an appropriate vehicle for the transmission of some ideas on the subject of requests for information or research specimens. For several years now the Research Materials Information Center has been referring inquiries for single crystals to commercial sources and to individuals w^o have produced crystals in the course of their own research and who have been kind enough to inform the Center that they are willing to lend or donate their crystals to others. Comments by many of the latter group indicate that, all too often, there is unnecessary correspondence and delay in such transactions caused by simple carelessness on the part of the requester. In addition, the subsequent fate of the donated crystal and the results of studies made with it frequently remain a mystery to the supplier, particularly in the cases where it is passed on to others by the original recipient. This last is frequently mentioned and was emphasized strongly in a recent survey on the status of crystal growth in the U.S.1 1 Status of Crystal Growth in the United States, D. S. Billington and G. C. Danielson, GRNL-RMIC-10 (December 1968), p. 4. "One indictment of the rest of the solid state community by the crystal growers is that the average scientist is too little concerned with the quality of the crystal he uses in his research and, as a consequence, much of the research reported is of little ox no value. Another serious objection is that more research is often involved in the preparation of the crystal than in the physical measurements. Yet the crystal grower may receive no more than a 'thank you' in the 'Acknowledgements' of the paper. This matter is so serious that some crystal growers will soon refuse to furnish crystals unless they are direct participants in the research." iii Such comments range from suggestions to complaints on the part of the crystal grower; and they are remarks that many are, understandably, reluctant tc make to their colleagues. In the hope, therefore, that the path of both the user and the grower of crystals may be somewhat eased and that the suggestions be taken in the spirit offered, a summary follows: 1. In requesting a crystal, be as specific as possible. List size, purity, orientation, desired dopant and amount, and any other required properties. There is no point in receiving a crystal that might be worthless to you but adequate for other purposes. 2. Specify the nature and the purpose of the work to be done on the crystal. The crystal grower is a fellow scientist and has an interest in studies complementary to (and not competitive with) his own. His crystal supply is very limited, and it should be assumed that he must be selective in distributing it. 3. Be sure to provide the original supplier personally with any data taken from the sample. (Publication is a slow process, and he might never see the paper.) Each separate study can be a further characterization of the crystal and, if recorded, add to its value as a research specimen. 4. Above all, give full acknowledgement to the supplier of the crystal, specifying (if applicable) his methods of characterization and the nature of his studies of the material. This is not only courteous but could be useful correlative information to the readers of your paper.

  • Conventional and Microwave Hydrothermal Synthesis and Application of Functional Materials: a Review
    materials Review Conventional and Microwave Hydrothermal Synthesis and Application of Functional Materials: A Review Guijun Yang and Soo-Jin Park * Department of Chemistry, Inha University, 100 Inharo, Incheon 402-751, Korea; [email protected] * Correspondence: [email protected]; Tel.: +82-32-876-7234 Received: 5 March 2019; Accepted: 9 April 2019; Published: 11 April 2019 Abstract: With the continuous development and progress of materials science, increasingly more attention has been paid to the new technology of powder synthesis and material preparation. The hydrothermal method is a promising liquid phase preparation technology that has developed rapidly during recent years. It is widely used in many fields, such as the piezoelectric, ferroelectric, ceramic powder, and oxide film fields. The hydrothermal method has resulted in many new methods during the long-term research process, such as adding other force fields to the hydrothermal condition reaction system. These force fields mainly include direct current, electric, magnetic (autoclaves composed of non-ferroelectric materials), and microwave fields. Among them, the microwave hydrothermal method, as an extension of the hydrothermal reaction, cleverly uses the microwave temperature to compensate for the lack of temperature in the hydrothermal method, allowing better practical application. This paper reviews the development of the hydrothermal and microwave hydrothermal methods, introduces their reaction mechanisms, and focuses on the practical application of the two methods. Keywords: hydrothermal method; microwave hydrothermal method; functional materials; application 1. Introduction During the process of continuous development of materials science, the research and development of new processes for material preparation and synthesis has always been an important part. For a long time, researchers have been searching for a material synthesis method with limited pollution, easy operation, excellent product performance, and low production cost [1–3].

The monodisperse core-shell Fe3O4 nanoparticles have been successfully synthesized by short times (3 hours) hydrothermal method at 220 oC from FeCl3, citrate, urea and PEG.The as-synthesized samples have been characterized using X-Ray Diffraction (XRD), Transmission Electron Microscope (TEM), Bruneur-Emmet-Teller (BET) surface area analyzer, and Vibrating Sample Magnetometer (VSM). The XRD result shows the as-synthesized products are pure Fe3O4. The TEM image shows the magnetite nanoparticles have monodisperse core-shell shape. The BET result shows the magnetite nanoparticles have 650.757 m2/g surface area. The hysteresis curve shows the magnetite nanoparticles exhibit super paramagnetic properties. This simple method obtained 60 nm core-shell Fe3O4 particles with super paramagnetic, high surface area as well as hydrophilic properties. Those properties are promising for various biomedical application. The advantages of simple and short times methods with high quality of product make this method very promising to be applied.

Received: 2 Aug. 2019, Revised: 22 Nov. 2019, Accepted: 23 Nov. 2019 Published online: 1 Jan. 2020 Abstract: An ideal crystal is built with regular and unlimited recurring of crystal unit in the space. Crystal growth is defined as the phase shift control. Regarding the diverse crystals and the need to produce crystals of high optical quality, several many methods have been proposed for crystal growth. Crystal growth of any specific matter requires careful and proper selection of growth method. Based on material properties, the considered quality and size of crystal, its growth methods can be classified as follows: solid phase crystal growth process, liquid phase crystal growth process which involves two major sub-groups: growth from the melt and growth from solution, as well as vapour phase crystal growth process. Methods of growth from solution are very important. Thus, most materials grow using these methods. Methods of crystal growth from melt are those of Czochralski (tensile), the Kyropoulos, Bridgman-Stockbarger, and zone melting. In growth of oxide crystals with good laser quality, Czochralski method is still predominant and it is widely used in the production of most solid-phase laser materials. Keywords: Crystal growth; Czochralski method; Kyropoulos method; Bridgman-Stockbarger method. A special method is used for each group of elements depending on their usage and importance of their impurity, or consideration of form, impurity and size of crystal.

    Journal of Siberian Federal University. Engineering & Technologies 4 (2009 2) 400-408 ~ ~ ~ УДК 669:621.315.592 Synthesis of Ca4GdO(BO3)3 Single Crystals using Czochralski Method Robert Möckel*, Margitta Hengst, Christoph Reuther and Jens Götze TU Bergakademie Freiberg, Institute of Mineralogy, Brennhausgasse 14, D-09596 Freiberg, Germany 1 Received 16.11.2009, received in revised form 03.12.2009, accepted 18.12.2009 The oxoborate Ca4GdO(BO3)3 (GdCOB) is a potential material for advanced industrial applications because of its optical and electric properties. High quality single crystals of GdCOB have been grown from a melt using the Czochralski method. Single crystals of laboratory scale are of good optical quality showing no macroscopic defects like cracks, inclusions or discolouration. Crystals in [001] direction reveal regular growth, whereas crystals in [010] are of asymmetric shape but show less difficulties during the growth process. Keywords: single crystal growth, Czochralski, oxoborate, Ca4GdO(BO3)3. 1. Introduction First investigations on the system REE2O3–CaO–B2O3 go back to the late 1960s, early 1970s, when Kindermann took care of the whole system [1]. Most of these early syntheses were realized by solid state reactions. Later, Ca4REEO(BO3)3 (REECOB) was synthesized and described by Norrestam & Nygren [2], who produced the materials by simple solid state reactions of stoichiometric mixtures as well. They showed that most trivalent REE like La, Nd, Sm, Gd, Er, and Y fit into the crystal lattice crystallizing isostructurally. First analysis of the crystallographic structures revealed analogies to calcium fluoroborate (Ca5F(BO3)3) and also to well known structure of common fluorapatite (Ca5[F/(PO4)3]).

  • Silver Enrichment in the San Juan Mountains, Colorado
    SILVER ENRICHMENT IN THE SAN JUAN MOUNTAINS, COLORADO. By EDSON S. BASTIN. INTRODUCTION. The following report forms part of a topical study of the enrich­ ment of silver ores begun by the writer under the auspices of the United States Geological Survey in 1913. Two reports embodying the results obtained at Tonopah, Nev.,1 and at the Comstock lode, Virginia City, Nev.,2 have previously been published. It was recognized in advance that a topical study carried on by a single investigator in many districts must of necessity be less com­ prehensive than the results gleaned more slowly by many investi­ gators in the course of regional surveys of the usual types; on the other hand the advances made in the study of a particular topic in one district would aid in the study of the same topic in the next. In particular it was desired to apply methods of microscopic study of polished specimens to the ores of many camps that had been rich silver producers but had not been studied geologically since such methods of study were perfected. If the results here reported appear to be fragmentary and to lack completeness according to the standards of a regional report, it must be remembered that for each district only such information could be used as was readily obtainable in the course of a very brief field visit. The results in so far as they show a primary origin for the silver minerals in many ores appear amply to justify the work in the encouragement which they offer to deep mining, irrespective of more purely scientific results.
