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.

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 manufacture and use of the powders of non-ferrous metals has been taking place for many years in what was previously Soviet Russia, and a huge amount of knowledge and experience has built up in that country over the last forty years or so. Although accounts of the topic have been published in the Russian language, no English language account has existed until now. Six prominent academics and industrialists from the Ukraine and Russia have produced this highly-detailed account which covers the classification, manufacturing methods, treatment and properties of the non-ferrous metals ( aluminium, titanium, magnesium, copper, nickel, cobalt, zinc, cadmium, lead, tin, bismuth, noble metals and earth metals). The result is a formidable reference source for those in all aspects of the metal powder industry. * Covers the manufacturing methods, properties and importance of the following metals: aluminium, titanium, magnesium, copper, nickel, cobalt, zinc, cadmium, noble metals, rare earth metals, lead, tin and bismuth. * Expert Russian team of authors, all very experienced * English translation and update of book previously published in Russian.

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.

The Coming of Materials Science both covers the discipline of materials science, and draws an impressionistic map of the present state of the subject. The first chapter examines the emergence of the materials science concept, in both academe and industry. The second and third chapters delve back into the prehistory of materials science, examining the growth of such concepts as atoms, crystals and thermodynamics, and also examine the evolution of a number of neighbouring disciplines, to see what helpful parallels might emerge. The book contains numerous literature references. Many refer to the earliest key papers and books, while others are to sources, often books, offering a view of the present state of a topic. Early references are to the past but as the book continues, it brings the reader up to date with more recent sources. The author, Professor Robert Cahn FRS, has striven to be critical about the history of the discipline of materials science and to draw general conclusions about scientific practice from what he has discovered about the evolution of materials science. Further issues that the book highlights include: What is a scientific discipline? How do disciplines merge and differentiate? Can a discipline also be interdisciplinary? Is materials science a real discipline? A large range of themes is presented in the book and readers are invited to interact with the author if they reach alternative conclusions. This book is not just for reading and reference, but exists to stimulate thought and provoke discussion as well.
