reaction of silicon carbide to form silica price list

Ductile Iron News Home Page

A critical factor when choosing a silicon carbide grain is cost. A 90% silicon carbide gives the melt operator about 63% available silicon. If we compare the price of 90% silicon carbide with the Noveer 1, 1999 price of 75% ferrosilicon at 36.65 cents per pound of silicon, then a price of $462.00 a short ton would be an equivalent silicon price.
