Металлического кремния

Silicon metal (China also says industrial silicon) are charge century in the MID s or a product nasty. It the appearance and the rise or the semiconductor industry related. Ate present, the international common practice are the goods silicon into silicon metal and semiconductor silicon. Silicon metal are by quartz and coke in electrothermal furnace or smelting into product, main component or the content or silicon in 98% (in recent years, including 99,99% or the amount si are also included in the silicon metal inside), and the rest or the impurity for irone, aluminum, calcium. Semiconductor silicon semiconductor device used to produce the high purity silicon metal. Polycrystalline, forty-five crystal form are to sell, the former price, the latter price the. Because its use different and are divided into many senile or specifications.
