Author: Beryllium Chemistry and Processing
Author: Kenneth A. WalshPublisher: ASM International
ISBN: 0871707217
Category : Science
Languages : en
Pages : 592
Book Description
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.
Health Effects of Beryllium Exposure
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309111676
Category : Science
Languages : en
Pages : 108
Book Description
Beryllium is an important metal that is used in a number of industries-including the defense, aerospace, automotive, medical, and electronics industries-because of its exceptional strength, stability, and heat-absorbing capability. It is found in a variety of technologies, including nuclear devices, satellite systems, missile systems, radar systems, bushings and bearings in aircraft and heavy machinery, x-ray machines used for mammography, cellular telephone components, computer components, and connectors for fiber optics. To help determine the steps necessary to protect its workforce from the adverse effects of exposure to beryllium used in military aerospace applications, the U.S. Air Force requested that the National Research Council's Committee on Toxicology (COT) conduct an independent evaluation of the scientific literature on beryllium, provide risk estimates for cancer and noncancer health end points, and make recommendations about specific tests for surveillance and biomonitoring of workers. The request specified that two reports be produced to accomplish those tasks. The first is to provide a review of the scientific literature on beryllium, and the second will expand more critically on the review in considering the maximum chronic inhalation exposure levels that are unlikely to produce adverse health effects, in estimating carcinogenic risks, and in providing guidance on testing methods for surveillance and monitoring of worker populations and other specific issues detailed in the statement of task. In response to the U.S. Air Force request, COT convened the Committee on Beryllium Alloy Exposures, which prepared this first report. Health Effects of Beryllium Exposure : A Literature Review identifies the available toxicologic, epidemiologic, and other literature on beryllium that is most relevant for addressing the statement of task, focusing primarily on beryllium sensitization, CBD, and cancer.
Critical Mineral Resources of the United States
Author: K. J. SchulzPublisher: Geological Survey
ISBN: 9781411339910
Category : Business & Economics
Languages : en
Pages : 868
Book Description
As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
