Description of Germanium Wafer

Germanium is a grayish-white metal, shiny, hard, belonging to the carbon family, chemical properties similar to the same family of tin and silicon. Ge is insoluble in water, hydrochloric acid, dilute caustic solution, soluble in aqua regia, concentrated nitric acid, or sulfuric acid. It has two sexes, so it is soluble in molten alkali, peroxide-based, alkali metal nitrate, or carbonate, which is stable in the air. Ge is an appealing semiconductor that has many unique properties. Stanford Advanced Materials (SAM) produces Germanium Wafers with the highest possible density.
