Handbook on the Physics and Chemistry of Rare Earths Volume 9 Elsevier, 1987 Handbook on the Physics and Chemistry of Rare Earths volume 9 Elsevier, 1987 Edited by: Karl A. Gschneidner, Jr. and LeRoy Eyring ISBN: 978-0-444-87045-2 by kmno4 Handbook on the Physics and Chemistry of Rare Earths, edited by K.A. Gschneidner, Jr. and L. Eyring © Elsevier Science Publishers B.V., 1987 PREFACE Karl A. GSCHNEIDNER, Jr., and LeRoy EYRING o These elements perplex us in our rearches [sic], baffle us in our speculations, and haunt us in our very dreams. They stretch like an unknown sea before us- mocking, mystifying, and murmuring strange revelations and possibilities. Sir William Crookes (February 16, 1887) There are those who feel that the rare earth elements are destined to play an even greater role in our "high-tech" society in the future than they have in the past. This judgement is based upon the trend of increasing applications resulting from the electronic structures of these materials that lead to their unusual optical, magnetic, electrical and chemical properties so adaptable to the demands now being placed on materials. The "Handbook" seeks to provide topical reviews and compilations of critically reviewed data to aid in the design and fabrication of the required new materials. Four additional chapters in this tradition are the contents of this volume. The development of lasers containing rare earth species sparked an interest in glasses containing these elements. Reisfeld and J0rgensen discuss excited-state phenomena in vitreous rare-earth-containing substances. The description of the chemistry and crystal chemistry of complex inorganic compounds of the rare earths is continued by Niinist6 and Leskelfi from the previous volume. Here they consider the phosphates, arsenates, selenates and selenites, oxohalogen com- pounds and vanadates. Encapsulation and transport of charged hydrophilic species from an aqueous medium into a hydrophobic phase are promoted by ionophores. The properties and applications of rare earth complexes with synthe- tic ionophores are described by Biinzli. Finally, Shen and Ouyang review their own work and that of others in the application of rare earth coordination catalysts in stereospecific polymerization. These Ziegler-Natta type catalysts provide tools for, among other things, the design of electrically conducting polymers. CONTENTS Preface v Contents vii Contents of volumes 1-8 ix 58. R.

These include the development and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agencies on scien- tific and technical problems; invention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau's unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. Publications The results of the Bureau's research are published either in the Bureau's own series of publications or in the journals of professional and scientific societies. The Bureau itself publishes three periodicals available from the Government Printing Office: The Journal of Research, published in four separate sections, presents complete scientific and technical papers; the Technical News Bulletin presents summary and preliminary reports on work in progress; and Basic Radio Propagation Predictions provides data for determining the best frequencies to use for radio communications throughout the world.

  • Evaluation of Aqueous Systems

Salomon US Army ET & DL Fort Monmouth, NJ, USA February, 1986 CRITICAL EVALUATION: THE BINARY SYSTEM Solubility data for LiI03 in water have been reported in 37 publications (1-34, 44-46). At 298.2 K Shklovskaya et al. (5,7,8,11,14-20,22,23,25,27,28,44) reported the identical solubility of 43.82 mass %, and although the work spans a period of 10 years (1974-1983), it is not possible to determine the number of independent measurements in these 18 publi­ cations. The solubility of 43.30 mass % at 298.2 K reported in (24) is distinctly lower than all other findings and is therefore rejected. Unezawa et al. (33) reported the solubility to be about 76 g/lOO g H20 (43.2 mass %) over the temperature range of 278-343 K, and although this is an interesting result its qualitative nature led us to conclude that it should not be compiled. However the importance of this paper is that the authors identified the stable solid phase at room temperature as hexagonal LiI03 (i.e. the a-phase) which is consistent with other quantitative data as discussed below. A graphical summary of the solubility of LiI03 in water is given in the polytherm figure below. In all cases the equilibrated solid phase is the anhydrous salt. 370 350 330 T/K 310 290 270-I------.r-----.-----..----......----------. 42 43 44 45 46 47 48 mass % Figure 1.

    E^l Admin. NBS MONOGRAPH 25—SECTION 5 Refecii^M not to be ^ferlrom the library. Standard X-ray Diffraction Powder Patterns ^\ / U.S. DEPARTMENT OF COMMERCE S NATIONAL BUREAU OF STANDARDS THE NATIONAL BUREAU OF STANDARDS The National Bureau of Standards^ provides measurement and technical information services essential to the efficiency and effectiveness of the work of the Nation's scientists and engineers. The Bureau serves also as a focal point in the Federal Government for assuring maximum application of the physical and engineering sciences to the advancement of technology in industry and commerce. To accomplish this mission, the Bureau is organized into three institutes covering broad program areas of research and services: THE INSTITUTE FOR BASIC STANDARDS . provides the central basis within the United States for a complete and consistent system of physical measurements, coordinates that system with the measurement systems of other nations, and furnishes essential services leading to accurate and uniform physical measurements throughout the Nation's scientific community, industry, and commerce. This Institute comprises a series of divisions, each serving a classical subject matter area: —Applied Mathematics—Electricity—Metrology—Mechanics—Heat—Atomic Physics—Physical Chemistry—Radiation Physics— -Laboratory Astrophysics^—Radio Standards Laboratory,^ which includes Radio Standards Physics and Radio Standards Engineering—Office of Standard Refer- ence Data. THE INSTITUTE FOR MATERIALS RESEARCH . conducts materials research and provides associated materials services including mainly reference materials and data on the properties of ma- terials. Beyond its direct interest to the Nation's scientists and engineers, this Institute yields services which are essential to the advancement of technology in industry and commerce.

NATIONAL BUREAU OF STANDARDS The National Bureau of Standards' was established by an act ot Congress on March 3, 1901 The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau's technical work is per- formed by the National Measurement Laboratory, the National Engineering Laboratory, and the Institute for Computer Sciences and Technology. THE NATIONAL MEASUREMENT LABORATORY provides the national system of physical and chemical and materials measurement; coordinates the system with measurement systems of other nations and furnishes essential services leading to accurate and uniform physical and chemical measurement throughout the Nation's scientific community, industry, and commerce; conducts materials research leading to improved methods ol measurement, standards, and data on the properties of materials needed by industry, commerce, educational institutions, and Government; provides advisory and research services to other Government agencies; develops, produces, and distributes Standard Reference Materials; and provides calibration services. The Laboratory consists of the following centers: Absolute Physical Quantities- — Radiation Research — Thermodynamics and Molecular Science — Analytical Chemistry — Materials Science.
