Mo Molybdenum Physical Properties, Part 2. Electrochemistry

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."
