Product Description

Basic information:

1.Purity: 99.999% 5n high purity zone-refine germanium ingot

2.CAS No.: 7440-56-4

3. Main application:  mainly used as a semiconductor material for transistors.

 

Characteristics:

1.Lustrous, hard, grayish-white solid metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.

2.Purified germanium is a 'p-type' semiconductor material. 

3.Conductivity depends largely on added impurities. 

4.Attacked by nitric acid and aqua regia, but stable in water, acids, and alkalies in absence of dissolved oxygen, low toxicity.
