Semi-coke is light black; characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur and Low phosphorus; wildly applied to such industries as chemical industry, metallurgic industry, gas-making industry, etc.; used to produce Calcium Carbide,Ferrosilicon, FerroNickel,Silicon Carbide, Silico Manganese, Fertilizer, etc 1.Advantage of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer Price is cheaper than Met Coke High fixed carbon (84% max) Low ash (9% max) Low Phosphorus (0.03% max) Low Sulfur (0.4%max) High specific resistance High chemical activity High conductivity to lower the electric power
