Structural characterization showed that the mixed compounds exhibit disordered (α) and ordered (β) phases for temperatures above and below about 200− 250 K, respectively, in agreement with their monoalkali correspondents. Vibrational and dynamical properties are strongly influenced by the cation environment; in particular, there is a red shift in the band energies of the librational and bending modes with increasing lattice size as a result of changes in the bond lengths and force constants. Additionally, slightly broader spectral features are observed in the case of the mixed compounds, indicating the presence of structural disorder caused by the random distribution of the alkali-metal cations within the lattice.

The objective of this study is trying to make use of this material in a new way as protective thin films on engineering materials. The brittle nature of the silicides can thus be compensated by the ductile bulk material and the surface corrosion resistance can be improved. The choices of thin film constituents are targeted at the transition metal elements including titanium (Ti, Z = 22), chromium (Cr, Z = 24), iron (Fe, Z = 26) and nickel (Ni, Z = 28) in combination with silicon (Si, Z = 14) to form the binary-component intermetallic compounds by means of ion-beam sputter deposition, which was carried out in an ultrahigh vacuum (UHV) chamber at 10 -6 Pa. The chosen substrate material is AISI 304 stainless steel. Thin film characterisations were conducted by means of surface analysing instruments: X-ray photoelectron spectrometer (XPS) and grazing incidence X-ray diffractometer (GIXRD).

  • The Mechanism Behind the Calcium Aluminum Silicide Ternary Structural Preference and the Origin of Its Semimetal Behavior
    THE MECHANISM BEHIND THE CALCIUM ALUMINUM SILICIDE TERNARY STRUCTURAL PREFERENCE AND THE ORIGIN OF ITS SEMIMETAL BEHAVIOR by Torey Elizabeth Semi A thesis submitted to the Faculty and the Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Applied Physics). Golden, Colorado Date Signed: Torey Elizabeth Semi Signed: D.M. Wood Thesis Advisor Golden, Colorado Date Signed: Dr. Thomas Furtak Professor and Head Department of Engineering ii ABSTRACT CaAl2Si2 is the prototype of the CaAl2Si2 class of Zintl structures established to be useful as thermoelectrics. We propose that CaAl2Si2 be interpreted as an ordinary covalently bonded, tetrahedrally coordinated quasi-semiconductor consisting of a large distortion of the wurtzite structure with the almost fully ionized Ca inserted at an interstitial site. We support this interpretation via a structural mapping and calculations for both a charged binary primitive cell and a Si4 primitive cell. Our intent is to explain the unusual structure of the CaAl2Si2 class of semiconductors, the origin of its semimetallic behavior, the basis for its stability and the effect of substituting other column II atoms for Ca on these properties. To be clear, this work does not examine the nature of the true band gap, or the transport coefficients of CaAl2Si2. GW corrections are not discussed, in view of the focus on the origins of stability of this peculiar structure. iii TABLE OF CONTENTS ABSTRACT . iii LIST OF FIGURES . vi LIST OF TABLES . xi ACKNOWLEDGMENTS . xii CHAPTER 1 INTRODUCTION . 1 1.1 Thermoelectric Materials . 2 1.2 Thermoelectric Efficiency .

  • Dissolution and Clarification of Rertr Silicide Fuels*
    DISSOLUTION AND CLARIFICATION OF RERTR SILICIDE FUELS* George C. Rodrigues E. 1. du Pont de Nemours Co. Savannah River Laboratory Aiken, SC 29808 XA04C1501 Abstract SRP may reprocess spent REM fuel as early as FY-85. Candidate RERTR fuels include uranium oxides, aluminides, and sicides. Much less is known about the behavior of uranium sicides during Purex reprocessing than either uranium oxides or aluminides. Studies were performed at SRL with RERTR silicide fuels to ensure their reprocessability. The results of dis- solution and head-end clarification studies with both unirradiated and irradiated fuel are presented. Introduction Highly enriched uranium fuels from a number of foreign and domestic research and test reactors are currently reprocessed at the Department of Energy's (DOE) Savannah River Plant (SRP). The objective of the Reduced Enrichment Research and Test Reactor (RERTR) program is to demonstrate on- version of these reactors to low enriched uranium (LEU) fuels to reduce the potential for diversion of highly enriched uranium. Ideally, this conver- sion should be accomplished without changing the fuel configuration or de- grading reactor performance. Conversion to LEU under these constraints requires that the new fuel elements contain up to 41/2 times as much total uranium. Advanced powder metallurgy fabrication techniques utilizing high density oxides, aluminides, and sicides should produce reliable fuels with uranium loadings in the desired range. Candidate silicide intermetallic compounds are U3Si, U3Si2, and U3SiAl. While a good deal is known about reprocessing oxides and aluminidesl,2, information on reprocessing sicides is limited and dissolution of some uranium sicides has proven difficult. In addition, dissolved silicon can disrupt solvent extraction2j3.

    A4 PaAer firesenteed at lie 162d Meeti g of the Amzerican Institute of Electrical E-ngineers at Nez York, February 2&ti 1Q902. THE ELECTRIC FURNACE IN INDUSTRIAL CHEMISTRY. BY CHARLES B. JACOBS. In its early days the electric furnace labored under the burden of the prophecies of its wonderful possibilities and products, and seems to have been more or less associated in the popular mind with the production of diamonds from amorphous carbon, the formation of gems and precious stones from cheap and plentiful materials, and other somewhat sensational operations which had a tendency to obscure, for a time, the knowledge of its useful- ness in the field of industrial chemistry. Notwithstanding the fact that DeChalmot, the Cowles brothers and others, had been operating the electric furnace for some years in the production of alloys from very refractory ores, it was not until Acheson produced carbide of silicon, Willson obtained carbide of calcium in commercial quantities, and Moissan pub- lishbd his scientific investigations in Le Four Electrique, that the value of the electric furnace for the production of substances use- ful in the arts began to be generally recognized. Since that time, however, its field of usefulness has been steadily increasing until it is now obtaining recognition as an im- portant factor in industrial chemistry. Reference to the patent lists of the various countries will show an immense variety of electric furnaces, but they may all be classified under three general types which have been modified in numerous ways to meet the special requirements of the var- ious processes for which they are intended.

  • BLABER- a Review of the Optical Properties of Alloys and Intermetallics for Plasmonics
    A review of the optical properties of alloys and intermetallics for plasmonics M G Blaber, M D Arnold and M J Ford* Institute for Nanoscale Technology, Department of Physics and Advanced Materials, University of Technology Sydney, PO Box 123, Broadway, NSW 2007, Australia *[email protected] Abstract. Alternative materials are required to enhance the efficacy of plasmonic devices. We discuss the optical properties of a number of alloys, doped metals, intermetallics, silicides, metallic glasses and high pressure materials. We conclude that due to the probability of low frequency interband transitions, materials with partially occupied d-states perform poorly as plasmonic materials, ruling out many alloys, intermetallics and silicides as viable. The increased probability of electron-electron and electron-phonon scattering rules out many doped and glassy metals. Contents 1. Introduction 2.

Introduction As nanofabrication techniques become increasingly fast and accurate, the performance of plasmonic systems relies less and less on structure fabrication and more on the fundamental limitations of the underlying materials. Plasmonics has seen an exponential growth, due mainly to the sheer diversity of applications, from optical cloaking [1] to superlensing [melville2005, pendry2000] as well as single molecule surface enhanced raman spectroscopy [2], parasite therapy [3] and optical circuits[4] with high speed optical switching[5, 6].
