Handbook of Inorganic and Organometallic Chemistry / W. Wolfram. Tungsten. (System-Nr. 54) / Ergänzungsband / The Element

The present volume continues the edition of a number of supplement volumes dealing with the elements tungsten and molybdenum. Technology and metallurgy of molybdenum and tungsten have been described in the respective volumes A 1. Tungsten Supplement Volume A 2 has been published and comprises the nuclear and atomic properties, sections on the clusters and the vapor, the electronic structure, the lattice dynamics, and the basic crystallographic properties. The present volume A/3 deals with the relationships between lattice defects and mechanical properties. Each of the subsequent chapters, concerning the thermal, electrical, magnetic, and optical properties, has a somewhat larger scope than the corresponding chapter in the Molybdenum Supplement Volumes. Within these chapters, some noteworthy facts are the following: the melting point of tungsten is the highest of all metals, i.e., 3695 K, the behavior of the current carriers has been studied in great detail by numerous methods, and the emissivity characteristics have received much attention above all because of the high melting point. Another special feature is the very intense study of all surface properties and the phenomena, which will be described in a forthcoming volume.
