Germanium Powder High Purity Metals CAS 7440-56-4 Ge Semiconductor Material
Breif introduction of  Germanium Powder
 
Germanium is a chemical element with symbol Ge and atmoic number  32.
 
Pure germanium is a semiconductor with an appearance similar to elemental silicon.
 
Like silicon, germanium naturally reacts and forms complexes with oxygen  in nature.

Application of Germanium Powder
 
1. Isolated germanium is mainly used as a semiconductor material for transistors.
 
2. The first generation of semiconductors were based solely on germanium.
 
3. However, most of today’s semiconductor production is based on silicon and germaniums use in electronics are in fibre-optic systems, infrared optics and in solar cell applications.
 
4. Used for electronic industry,solar energy industry,metallurgy, chemical reagen
 
Properties of Germanium Powder
 
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.
