Germanium: A review of its US demand, uses, resources
It is a lustrous, hard-brittle, grayish-white metalloid with atomic number of 32 and atomic mass of 72.64 u. Germanium was first isolated by Clemens Winkler in 1886 from the mineral argyrodite (Ag 8 GeS 6) [1]. The metalloid is present as a trace element in Earth's crust with an average concentration of 1.6 ppm [2], [3].
