Characteristics: | Germanium dioxide is a stable white powder, which is most commonly extracted from sphalerite zinc ore and brown coal ash.Germanium concentrate can be processed by chlorine distillation to produce germanium tetrachloride (GeCl4). This form of germanium dioxide has a hexagonal crystal structure and is soluble in water at a rate of 4.5 grams per liter (25 ° C). |
Applications: | Germanium dioxide is used as a catalyst in the production of PET plastics used for heated beverage bottles, as well as raw material of metal germanium and other germanium, semi-conductor material and spectral analysis.It can also be used to manufacture optical glass phosphor, as well as catalyst, color film and polyester production. |
