Ferro-silicon can be substituted for metallurgical-grade silicon carbide, especially in iron foundries. The leading ferro-silicon producing countries are (in decreasing order of ferro-silicon production) China, Russia, Norway, and Ukraine; they accounted for over 85% of total ferro-silicon production.
Silicones - Essential Chemical Industry
Silicon is first converted into chlorosilanes, e.g. RSiCl 3, R 2 SiCl 2 and R 3 SiCl, where R is an organic group. When chloromethane is passed through heated silicon at about 550 K under slight pressure and in the presence of a copper alyst (often copper itself but other copper-containing materials can be used, for example, brass or copper(II) chloride) a volatile mixture of chlorosilanes
