Introduction of industry

Product Series

Polycrystalline silicon is a form of silicon, shines with gray metallic luster. Density of 2.32-2.34. The melting point of 1410℃. The boiling point of 2355℃. Dissolves in a mixture of hydrofluoric acid and nitric acid, doesn’t dissolve in water, nitric acid and hydrochloric acid. Rigidity is between germanium and quartz. Crisps under room temperature, easily breaks when cutting. Becomes ductile when heated to 800℃ and above, noticeably deforms when heated to 1300℃. Not lively at room temperature, reacts with oxygen, nitrogen, sulfur and others in high temperature. Under the high temperature melting state, possesses a larger chemical activity, can function with almost any material. Has semiconductor properties, it is a very important excellent semiconductor material and is a raw material for the preparation of silicon and solar batteries, it is the cornerstone of the global electronic industry and photovoltaic industry.
