Germanium is a gray-white metalloid, and in its pure state is crystalline and brittle, retaining its lustre in air at room temperature. It is a very important semiconductor material. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with an impurity of only one part in 10-10; Germanium doped with arsenic, gallium, or other elements for use as a transistor element. Its application as a semiconductor provides the largest use for germanium.
