Silicon Metal 441 553 3303 2502 2202 Strict quality control low P & B Si: 99% min Fe: 0.5% max Al: 0.5 Ca: 0.3%

Production Description: Industrial silicon, which can also be called metal silicon, is silver grey or black with metallic luster. It has the function of high melting point, good heat resistance, high oxidation resistance, high resistivity. It is the essential basic raw materials of many high-tech industries. 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 etc. In chemical industry, And also regarding the no-ferroalloy's dditive, deoxidize, silicon-steel etc alloys adding materials. It's applied to mechanical, chemical, alloys, electronic, medicineindustry etc. Package: In plastic woven bags of 1000kgs net each or we can negotiate
