Standard:

             

It is made by deoxidizing high quality silicon stone in the electric arc furnace, the reducer normally are petroleum coke or charcoal. When smelting Aluminium-alloy, add some Si Metal with the Si purity above 98%, the capability of Aluminium-Alloy will be obviously improved. The Si Metal is also the excellent material for producing super-pure Silicon in electro-industry.
