Feature:
Black silicon metal is produced at high temperture in an electric resistance type furnace with quarts sand and pertroleum coke as its raw marterials. Its hardness is between fused alumina and synthetic diamond.
Application:
The Silicon metal possesses quite widely application.For Example,to produce organic-Si ,Alluminum alloy ,Ferro alloyetc.in chemical industry,And also regarding the non-ferroalloy\'s dditive,deoxidize,silicon-steel etc alloys adding materials.It\'s applied to mechanical,chemical,alloys,electronic,medicineindustry etc.
