Abstract:

A state-of-the-art survey and data sheet compilation on elemental boron is presented. The thorough literature search uncovered 304 references which were evaluated for information and data on the 1 reduction preparation methods, 2 zone-refining and melting techniques, 3 crystal structures, 4 electrical properties, 5 optical properties, 6 thermal and thermodynamic properties, 7 physical and chemical properties, 8 metallurgy and mechanical properties, 9 applications, 10 availability and suppliers. Major emphasis was the characterization of borons semiconductive and acoustic properties with respect to potential semiconductor delay-line devices. Detailed information on the various methods of preparing pure boron and the resulting crystal structures plus properties are summarized in tables. Author
