Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys.
Metallic silicon is a product made of quartz and coke smelted in an electric furnace. The content of the main component silicon is about 98%, and the other impurities are iron, aluminum, calcium, etc.
In industry, silicon metal is usually produced by reducing silicon dioxide by carbon in an electric furnace. Chemical reaction equation: the purity of silicon prepared by SiO2+2C Si+2CO is 97 98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with purity of 99.7~99.8%.
Metal silicon particles: 1-200mm
silicon metal should be used to produce organic silicon, produce high-purity semiconductor materials and prepare alloys with special purposes.
(1) Production of silicone rubber, silicone resin, silicone oil and other silicone.
(2) Manufacture high-purity semiconductors.
(3) Prepare alloy.
(4) It is an excellent antioxidant in refractory and powder metallurgy industries.
Our company can provide various specifications and models of metal silicon blocks, particles and powders according to customer requirements.
