Abstract

The metal beryllium (Be) does not occur native, but can be obtained by the electrolysis of its fused compounds or by the reduction of the oxide or fluoride. Beryllium is a white metal with a specific gravity of about 1·85, and is thus much lighter than aluminium. The metal is employed in the production of special alloys, mainly with copper, but also with iron and nickel, and in nuclear reactors as a source of neutrons. The ore from which beryllium is obtained is beryl, Be3Al2(Si6O18) which is available as a by-product in the mining of mica and feldspar deposits in pegmatites. The only other beryllium-bearing mineral described here is chrysoberyl, BeAl2O4. Both beryl and chrysoberyl are used as gemstones.
