Product Name:Silicon
English Name:Silicon
CAS No.:7440-21-3
Aliases:Silicon powder, Silicon metal, Crystalline silicon
Molecular Formula:Si
Physical Properties:Silicon is a hard and brittle solid with a bluish-gray metallic luster and a diamond cubic crystal structure. It has a density of about 2.33 g/cm³, a melting point of 1414°C, and a boiling point of 3265°C. It is relatively stable at room temperature, insoluble in water, soluble in alkali solutions, and capable of reacting with halogens. Its electrical conductivity lies between conductors and insulators, making it a typical semiconductor material.
Uses:Silicon is a core material for the semiconductor and photovoltaic industries, used to manufacture integrated circuits, solar cells, and other devices. In the chemical industry, it is used to synthesize organosilicon monomers. In metallurgy, it serves as an additive for aluminum alloys and special steels.
Technical Specifications:
