OFF-Grade Silicon Metal suppliers Brief introduction: Silicon is a very commonplace element in earth that widely exists in rock, sand and earth. It is the second richest element in the earth’s crust. For its high melting point, good heat resistance, high resistivity and superior oxidation resistance, it’s widely used in modern industry as know by people as the “industrial glutamate” But it’s mainly exist by the form of silicon dioxide or silicate. It can be extract into elementary substance, which we can Silicon Metal. Processed by electronic arc furnace from materials of clays, silica sand and stone.It is silver gray or dark gray powder with metallic luster. Can be used in semi-conductor, metal ceramic, metallurgy, solar industries. Silicon metal includes several models by different purity from 98% to 99.9% or even higher. Among those models, silicon metal below 99.5% are usually used in metallurgical industry, such like aluminum alloy. Besides those conventional models, there is also off grade silicon metal which purity lower than common ones. Features and usage: * As an additive to non-ferrous alloys, industrial silicon is also used as an alloying agent for silicon steel with strict requirements, and as a deoxidizer for smelting special steels and non-ferrous alloys. * Silicon Metal鈥俰s Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear resistance and oxidation resistance. * Aluminum alloy ingot production, as additive of silicon.
