HC silicon  is a by product comes from silicon metal plant. It deposits on the bottom of the melting furnace, and has to be cleaned out in months interval. But with technological development, the interval has prolonged from three months to six months. So the output of these products are limited. We collect and select this product from bigger Silicon metal factories all around China.

Advantage

It is main used in foundries. As you know the cast iron contain C: 2-4%, Si: 1-3%, and Carbon and silicon are the main elements affecting the microstructure of cast iron.High Carbon Silicon has made carbon alloyed in it, so it can provide the two elements effectively. Lately it also be used in steel making, especially steel scraps melting. It serves as deoxidizer and efficient heating agent (Si&C: 6.58kcal/g, 1.24kcal/g each) and recarburizer. With Si&C at least 90%, the impurity is very less, so the input is easy to control.
