The ferro silicon powder takes the coke, scrap steel, and silica as raw materials ,which is made by the electrosmelting.
The ferro silicon powder is bright grey, and the density is small. The more silicon, the lower proportion. According to the content of the silicon, it can be divided into industrial ferrosilicon (Si > 97%, iron does not exceed 1.5 percent) ,and the ferro silicon of different contents of silicon ,95%, 75%, 65% and 45%, etc.
