The production and availability of thirteen high-purity metals are discussed in this report. Information about the purest available polycrystalline and single crystal forms of each of the metals is presented. Also included is information about less pure forms of the metal, usually including a grade which might be defined as commercially pure. Some of the newer techniques for analyzing or characterizing the purity of the metals are discussed without including methods of chemical analyses. The thirteen metals covered by this report include the refractory metals molybdenum, tungsten, columbium, tantalum, and rhenium; special light metals, beryllium, and titanium and metals with an intermediate melting point, iron, nickel, chromium, vanadium, and zirconium. The semi-metal, boron, is the thirteenth element. Individual sections for each of the metals are presented in alphabetical order.

NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.
