Tungsten and Its Compounds is a three-chapter text that explores the history, properties, production, and use of tungsten and its related compounds. The first chapter deals with the discovery, applications, ore occurrence, and production of tungsten. The second chapter describes the physico-chemical properties of elemental tungsten, including the structural, thermal, optical, electrical, and mechanical properties, as well as its preparation, production, reactivity, adsorption, electrochemical properties, and analytical aspects. This chapter also examines tungsten's metallographic properties, such as melting, powder metallurgy, singe crystals, and polycrystallinity. The third chapter reviews the properties of tungsten with other metals, metalloids, acids, and salts. This book is of value to inorganic, organic, and analytical chemists, as well as chemistry teachers and students.

Why does someone write a book about Tungsten? There are several reasons and precedents for this, the most important of which is that the last book on tungsten was written more than 20 years ago, in 1977, by St. W H. Yih and Ch T. Wang. During the intervening period there have been many new scientific and technological developments and innova tions, so it was not only our opinion but the view of many other members of the "tungsten family" that it was time to start writing a new book about tungsten. Preparations of the new book began in 1994. further impetus to the project was provided by the realization that in spite of this new knowledge having been presented at seminars or published in the technical press, a general acknowledgement of it by the majority of technicians and scientists is still far from being realized. It is our hope that this book will significantly contribute to a broader acceptance of recent scientific and technological innovations. An important prerequisite for such a project is the availability of a recently retired, experienced person willing to devote his time and talents to the tedious part of the exercise.

The present supplement volume, A 7, is the first of a triad, A 5 to A 7, dealing with the chemical reactions of metallic tungsten. It describes the reactions with inorganic and organic compounds, except for formation reactions of organotungsten compounds. Volume A 6, to appear at the beginning of 1988, will cover the reactions of tungsten with metallic elements. Volume A 5, in preparation for 1988/89, will contain the reactions with nonmetallic elements and, in addition, cover the electrochemistry of tungsten. With the appearance of this last volume, the present knowledge of the chemistry of tungsten will be compiled in more than 1000 pages. In the Gmelin main volume on tungsten, published in 1933, the presentation of the information then available on the same subject required less than 6 pages. This enormous increase in relevant data over the last fifty years is stupefying, considering the fact that tungsten is a rather inert metal which is resistant to most chemical agents up to high temperatures. With afew exceptions, in fact, it was not so much the reactions of bulk tungsten which attracted the interest of the experimenters as the reactions taking place at its surface. This comes about for practical as well as scientific reasons.

Non-sag (NS) tungsten is a dispersion-strengthened microalloy with elemental potassium, which is contained as microscopic bubbles in the tungsten lattice. Under working conditions in an incandescent lamp the potassium is a gas under high pressure. These gas bubbles essentially prevent the recrystallization of the tungsten wire and are responsible for the outstanding creep resistance of NS tungsten at the extremely high temperatures of a glowing lamp filament. More than 90% of NS tungsten is used for incandescent lamps. In addition, small amounts are used as defroster heating wires in automobile windshields and as heating wire coils for aluminium evaporation in metallization applications. The presented papers deal with the chemical reactions and the chemical compounds occurring along the path from tungsten raw materials to the final NS tungsten filament; a compendium of present knowledge on the different chemical aspects of NS tungsten manufacture is presented. It is composed of nine individual papers, each of them written by experts working in the field.

The Chemistry of Chromium, Molybdenum and Tungsten deals with the chemistry of chromium, molybdenum, and tungsten. The discovery and history, occurrence and distribution, and production of all three elements are discussed, along with their industrial uses, preparation, and allotropes; nuclear, physical, and chemical properties; biological activities; and analytical chemistry. Organized into three sections, this volume begins with an overview of the history, occurrence and distribution, and production of chromium, molybdenum, and tungsten, as well as their industrial uses, preparation, and allotropes; nuclear, physical, and chemical properties; biological activities; and analytical chemistry. The intermetallic phases in binary alloys of all three elements are also considered, along with their oxidation states and respective compounds including compounds with non-metallic elements; compounds of ?-acceptor ligands; organometallic complexes; and peroxy compounds such as peroxychromates, tetraperoxy molybdates, and peroxy tungstates. This book will be of interest to inorganic chemists as well as students and researchers in the field of inorganic chemistry.
