Pure 99.999% Ge Germanium Powder

1.Formula: Ge
2.CAS No.:7440-56-4
3.HS Code : 8112921090
4.Properties: Gray black powder, chemically similar to its group neighbors tin and silicon. Purified germanium is a 'p-type' semiconductor material. Conductivity depends largely on added impurities. Attacked by nitric acid and aqua regia, but stable in water, acids, and alkalies in absence of dissolved oxygen, low toxicity.
5.Storage Condition: It should be stored in a warehouse with cool, ventilated, dry, clean and chemical corrosion-free atmosphere.Moisture proof. Can not be mixed with acid and alkali products. During transportation, it should be rainproof and shockproof. When loading and unloading, be careful to prevent collision and rolling, and prevent mechanical damage.

Ge content ≥ 99.999%,melting point of 937.4 ℃, boiling point of 2800 ℃, density of 5.325g/cm3. Germanium powder is mainly used in semiconductor devices, coatings and alloy addition. Germanium powder can also be used in optical fiber communication systems, infrared optics, solar cells and other fields.
