The present volume completes the description of the interactions and chemical reactions of elemental tungsten with metallic elements, treating its reactions with antimony, bismuth, and the alkali and alkaline earth metals. The reactions of tungsten with these elements are in most cases confined to surface regions. Corrosion of tungsten and mutual solubility are usually very low. An exception is the W - Be system, in which several intermetallic phases are formed. The surface processes in some of the other systems covered in the present volume evoked considerable scientific and practical interest, documented by the large number of publications. This holds particularly for the Cs-on-W and Ba-on-W surface systems. Cs- and Ba-activated tungsten electrodes were and are used in many technical and laboratory appliances. One example is the Cs diode device for thermionic energy conversion. Surface ionization of Cs and W is widely applied in ion sources and for some time attracted great attention with respect to its potential use in ion rocket propulsion engines. Cs-on-W is also a logical system for basic research on chemisorption due to the propitious chemical, crystallographic, and atomic properties of adsorbent and adsorbate. The majority of existing models for the chemisorption bond has been experimentally checked on this system. The particular interest in the W - Cs and W - Ba systems is reflected in the large portion of the text (256 pages) devoted to these systems.

The volume describes physical properties of tungsten metal and covers specifically surface properties, electron emission, and field evaporation. Tungsten surfaces are probably the most extensively studied metal surfaces. Recently, experimentalists and theorists have focussed their interest on the atomic structure, lattice dynamics, and electronic properties of the W(100) surface. While the structure of the reconstructed low-temperature surface is well established, there are still unresolved problems concerning the structure at and above room temperature, the nature of the phase transition, and the driving force for the reconstruction. There are numerous and partly conflicting data on the surface energy, the self-diffusion parameters, and the work function of single-crystal and polycrystal tungsten surfaces. Electron emission, which is of fundamental importance for many applications, comprises thermionic, field, photofield, and photoelectric emission as well as emission induced by impinging electrons, atoms, or ions. Pioneering work in areas like thermionic or field emission is comprehensively discussed. Very recent studies of valence-band and core-level spectra moreover provide detailed information on intrinsic surface properties.

Under current U.S. EPA guidelines, particularly the Clean Air Act Amendments, stack gasses and the solid products of combustion require specialized treatment for removal of trace metals. This book presents a data-intensive assessment of the fate of trace metals during combustion. The data are derived from actual operating combustion systems, and the text emphasizes case studies that document trace metal fate control. Issues covered include metal volatility, metal reactions, and trace metal management through the enhancement or inhibition of specific chemical reactions.

This collection presents papers from a symposium on extraction of rare metals from primary and secondary materials and residues as well as rare metals extraction processing techniques used in metal production. The collection covers the extraction of less common or minor metals including elements such as antimony, bismuth, barium, beryllium, boron, calcium, chromium, gallium, germanium, hafnium, indium, manganese, molybdenum, platinum group metals, rare earth metals, rhenium, scandium, selenium, sodium, strontium, tantalum, tellurium, and tungsten. It also includes rare metals of low-tonnage sales compared to high-tonnage metals (iron, copper, nickel, lead, tin, zinc, or light metals such as aluminum, magnesium, or titanium and electronic metalloid silicon). Rare metal processing covers bio-metallurgy, hydro-metallurgy, and electro-metallurgy while novel high-temperature processes such as microwave heating, solar-thermal reaction synthesis, and cold crucible synthesis of rare metals are also addressed. Also included in this collection is the design of extraction equipment used in these processes from suppliers as well as laboratory and pilot plant studies.
