Steel & Iron Material for the Human Technology



Calcium Silicon is a potent deoxidizer and desulfurizer utilized in the production of  high grade steels. Although Silicon itself is a powerful deoxidizer, Calcium is by far more powerful. In addition, Calcium Silicon is  used to control the shape, size and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility, and impact properties of the final product
