Book excerpt: 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.

Book excerpt: 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.

Download or read book The Chemistry of Non Sag Tungsten written by L. Bartha and published by Elsevier. This book was released on 2013-10-22 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1993 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been remarkable growth throughout the 1980s in the chemistry of transition metal oxo complexes. Interest in what had been regarded as a mature area was rekindled in part by the recognition of the role of the oxo functionality as a 'spectator' ligand in catalytic alkene metathesis, and has been fueled by developments in the chemistry of transition metal porphyrin oxo complexes (including their roles in hydrocarbon oxidations and in alkene epoxidation and hydroxylation reactions), by continuing rapid evolution of our understanding of biologically relevent oxo transfer reactions, by extraordinary advances in the use of oxo complexes as catalysts for alkene hydroxylation and epoxidation, and most recently, by the remarkable catalystic activity demonstrated by high valent rehenium oxo alkyls. These development have been paralleled by significant advances in the syntheses of oxo complexes, including the preparations of 'low valent' oxo complexes and of high valent oxo alkyl complexes, and marked extentions of the rational synthesis of organometallic oxo complexes.
