Different grade of Silicon metal , different material .
Industrial Silicon metal has high content of Si element , so many steel mills sometimes will use industrial silicon metal instead of Ferro silicon when Ferro silicon’s price is higher .
Chemical Silicon metal is mainly used to produce solar and electronic.
Industrial Silicon metal and Chemical silicon metal can be processed to be Si powder for producing different of Ludox and other refractory product .
