MATERIAL OVERVIEW
| Appearance: | Hard and brittle, a silvery ash luster in trapezium-like bars.Melt germanium ingots cross-section is shaped as a trapezium. |
| Characteristics: |
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. |
| Production Methods: | Crucible direct method and suspension zone melting method are used in industrial production. |
| Applications: | Most of today’s semiconductor production is based on silicon and germanium that widely applied in semiconductor, aerospace control, nuclear physics, optical fiber communication, infrared optics, solar cells, chemical catalyst, biomedical and other fields. |
