Silicon metal is a widely used metallurgical grade silicon metal as an alloying agent in aluminum industry to enhance the strength of aluminum. The demand of metallurgical silicon metal is increasing as the aluminum industry has grown steadily with the increased aluminum alloys application in structural engineering, aircraft or automotive manufacture .
Metallurgical silicon metal 553 is produced by the carbothermic reaction of silica in electric arc furnace using carbon electrodes where the temperature exceeds 1800°C. Commercially produced metallurgical grade silicon metal is typically Si 98% above. details please refer to bellow form:

Application
1.Silicon metal is widely used in smelting alloy elements,as a reducing agent in many kinds of metal smelting.
2.Silicon metal is widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance.
3.Silicon metal powder is regarded as alloy additive, improve the steel hardenability in metallurgy and foundry industry.
4.Industrial Silicon metal powder is sublimated into monocrystalline silicon, which is widely used in highttech field as essential raw material for integrated circuit and electronic element.
5.Silicon metal are used in high-temperature material production in order to manufacture enamels and pottery.These also cater the demands of semiconductor industry by producing ultra-pure silicon wafers.
