Germanium is a metallic chemical element (symbol, Ge) with an atomic weight of 72.3. It is a grayish-white crystalline metal of great hard-ness and brittleness. Its melting point is 956? C (17500 F). Germanium may be alloyed with other metals but its known commercial uses require it to be in an exceptionally pure state. Less than one
