Product Description


Germanium powder
1.Formula: Ge

2.CAS No.:7440-56-4

3.HS Code : 8112921090

4.Properties: Lustrous, hard, grayish-white solid metalloid in the carbon group, 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%, resistivity ≥ 50Ω • cm (20 ± 0.5 ºC). Silver gray metallic luster, cuboid bar shape, hard and brittle, melting point of 937.4 ºC, boiling point of 2800 ºC, density of 5.325g/cm3. Germanium is mainly used as a semiconductor material for transistors. The first generation of semiconductors were based solely on germanium. However, most of today's semiconductor production is based on silicon and germanium use in electronics are in fibre-optic systems, infrared optics and in solar cell applications.
