1.Silicon metal is produced by the carbothermic reaction of silica in an electric  arc  furnace using carbon electrodes where the temperature in the main reaction zone of temperatures exceeds 1410ºC.

2.Silicon powder,it could be silver gray or dark gray  with metallic luster. With the characteristic of high melting point, good heat resistance, high resistivity and high antioxidant effect.

3.Silicon metal is the basic raw material of refractiry industry,such as refractory castables,stopper rod. 4.Silicon metal consumption by aluminum manufacturers has grown accordingly.
