Beryllium is a lightweight metal that is used for its exceptional strength and high heat-absorbing capability. Beryllium and its alloys can be found in many important technologies in the defense and aeronautics industries, such as nuclear devices, satellite systems, radar systems, and aircraft bushings and bearings. Pulmonary disease associated with exposure to beryllium has been recognized and studied since the early 1940s, and an occupational guideline for limiting exposure to beryllium has been in place since 1949. Over the last few decades, much has been learned about chronic beryllium disease and factors that contribute to its occurrence in exposed people. Despite reduced workplace exposure, chronic beryllium disease continues to occur. Those developments have led to debates about the adequacy of the long-standing occupational exposure limit for protecting worker health. This book, requested by the U.S. Air Force to help to determine the steps necessary to protect its workforce from the effects of beryllium used in military aerospace applications, reviews the scientific literature on beryllium and outlines an exposure and disease management program for its protecting workers.
This bibliography is the result of a "current awareness" service performed by the American Society for Metals, (ASM) under a purchase order with the University of California Lawrence Radiation Laboratory. The references were gathered from the world's leading journals, books, technical reports, dissertations, and patents for the period January 1961 through December 1962. In each section of this bibliography, books and journal articles appear first, arranged alphabetically by author. Anonymous articles are arranged alphabetically by journal name at the end of each grouping. These are followed by reports and patents arranged by report numbers. Translations are located in the groupings in accordance with their original form, i. e. book, journal, etc. Because of diversity of subject content, some references are located in more than one section.
This book introduces beryllium; its history, its chemical, mechanical, and physical properties including nuclear properties. The 29 chapters include the mineralogy of beryllium and the preferred global sources of ore bodies. The identification and specifics of the industrial metallurgical processes used to form oxide from the ore and then metal from the oxide are thoroughly described. The special features of beryllium chemistry are introduced, including analytical chemical practices. Beryllium compounds of industrial interest are identified and discussed. Alloying, casting, powder processing, forming, metal removal, joining and other manufacturing processes are covered. The effect of composition and process on the mechanical and physical properties of beryllium alloys assists the reader in material selection. The physical metallurgy chapter brings conformity between chemical and physical metallurgical processing of beryllium, metal, alloys, and compounds. The environmental degradation of beryllium and its alloys both in aqueous and high temperature condition are presented. The health and environmental issues are thoroughly presented the current requirements and established practices for handling beryllium in the workplace are available. A thorough list of references will assist the user of this book.
Excerpt from The Chemistry and Literature of Beryllium Discovery - In 1797 L. N. Vauquelin undertook to prove the chemical identity of the emerald and beryl, which had already been suspected by Haiiy, and in the course of his analytical research, discovered that a portion of the precipitate which had previously been supposed to be aluminium hydroxide, was thrown out of its solution in potassium hydroxide on boiling. He also found that this new hydroxide was soluble in ammonium car bonate, formed no alum and was in many ways different from aluminum. These observations led him to announce in a paper read before the Institute on Feb. 14, 1898 (1798; I),1 the dis covery of a new earth.

Reports of Government-supported research on the physical and process metallurgy of beryllium that were received at DMIC during the period 1958-1960, inclusive, are summarized, together with some reports and publications of foreign authors. No proprietary or classified information is included. In addition, reference is made to some of the more importa t writings on health hazards and safety procedures that appeared during the period covered. (Author).
Beryllium is a gray, brittle metal. The difficulty and expense of extracting Be from rocks are the main reasons for its obscurity. Prized for its light weight, durability, strength, and heat capacity, Beryllium is alloyed with other metals for use in jets, gyroscopes, jewelry, cameras, cell phones, golf clubs, watches, space telescopes, X-ray systems, trumpets and flutes, and nuclear reactors. An experiment simulating radioactive decay is included.
