Mo Molybdenum

Physical Properties, Part 2. Electrochemistry

By: Gerhard Czack,Gerhard Kirschstein,Vera Haase,Wolf-Dietrich Fleischmann,Dieter Gras

As was announced two years ago, the description of the physical properties of molybde num has now been completed in the present volume up to page 124. Whereas most properties, e.g., the electrical, magnetic, and optical properties, are dealt with in the usual manner, the results of studies of the atom and ion emission had to be presented in a revised form, comprising not only the most recent data but having in mind also the corresponding data for tungsten, which will be represented in a supplement volume now in preparation. The various modes of electron emission have also been studied in great detail. Many more pages (exactly 226 pages, as contrasted to three pages in the Main Volume) were needed to present the electrochemical data for molybdenum, which were published to an astonishingly great extent by Russian workers. The large volume of literature is due to the extensive industrial application of the metaL, cf. "MoLybdän" Erg.-Bd. A 1, 1977, and to its occurrence in various oxidation states. Thus the equilibrium between an Mo eLectrode and Mo ions or between an inert eLectrode and Mo ions is deaLt with in the chapters "Standard PotentiaLs" and "PotentiaLs", whereas kinetics and reaction mechanisms of the reduction and oxidation of Mo ions on a dropping mercury electrode and other inert eLectrodes can be found in the chapter "Polarography/ Voltammetry.

W Tungsten

Supplement Volume A4 Surface Properties. Electron Emission

By: Gerhard Czack,Gerhard Kirschstein,Wolfgang Kurtz,Frank Stein

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.

Be Beryllium

The Element. Physical Properties (continued) and Electrochemical Behavior

By: Gudrun Bär,Lieselotte Berg,Gerhard Czack,Dieter Gras,Vera Haase

The present Supplement Volume Beryllium A 3 continues and completes the description of the physical properties of the element, begun in Supplement Volume A 2, 1991, and also treats the electrochemical behavior of the metal. The unique combination of the Be properties, which was pointed out in Supplement Volume A 2, is also demonstrated in the following chapters of this Volume A 3: 13. Electrical Properties 14. Electronic Properties 15. Optical Properties. Emission and Impact Phenomena 16. Electrochemical Behavior Starting with the electrical properties, Be isarather good electrical conductor in centrast to what might be expected. Superconductivity was studied, especially on films. Quantum effects, which are more pronounced in Be than in most other metals, are the reason for numerous in vestigations of the magnetoresistance and the magnetic-breakdown effect. The basis for many of the characteristic properties is the unique nature of bonding in Be as a consequence of its peculiar electronic structure and the special shape of its Fermi surface which also gave rise to further numerous studies. Detailed cluster calculations were per formed to better understand the bonding in the metal. Regarding the optical properties, the high reflectivity of Be, particularly in the infrared region, makes it attractive for the fabrication of precision optical surfaces (mirrors); it is also useful for solar-collector surfaces in spacecraft applications. Emission and electron-and ion impact phenomena as well as neutron optics are also discussed.

The Element. Physical Properties

By: Lieselotte Berg,Gerhard Czack,Dieter Gras,Elisabeth Koch-Bienemann

Beryllium Supplement Volume A2 describes the properties of the bulk metal, the main emphasis being on the crystallographic structure and the structure-related (mechanical) properties. The great importance of this metal, for instance in nuclear and space technologies, results from its unique combination of properties, i.e., low density, extremely high elasticity modulus, and relatively high melting point. In addition, Be played a particular role in studying the fundamental mechanisms of deformation in the lattices of metals. On this basis, numerous factors contributing to the ductility or brittleness of Be are discussed. Thermal and magnetic properties complete the description of Be in this volume.
