Germanium dioxide is colorless crystal, which including faintly water soluble hexagonal crystal (stable at low temperature) and insoluble tetragonal system. Its transformation temperature is 1033℃. GeO2 is insoluble in water, which dissolve in alkali to form germanate salts. Tetragonal GeO2 is not stable when temperature below 1033℃, which transform into hexagonal one slowly. Germanium tetrachloride is the raw material.
