From the Latin word Germania , Germany. Mendeleev predicted the existence of Germanium in as ekasilicon, and the element was discovered by Winkler in The element is commercially obtained from the dust from smelters that process zinc ores. It is also recovered from combustion by-products of certain coals. Germanium can be separated from other metals by fractional distillation of its volatile tetrachloride. These techniques permit the production of germanium of ultra-high purity. The element is a gray-white metalloid. In pure state, the element is crystalline and brittle, retaining its luster in air at room temperature. It is a very important semiconductor. Zone-refining techniques have led to production of crystalline germanium for semiconductor use with an impurity of only one part in
