Calcined Anthracite Coal is also called "Carbon Raiser" or "Gas Calcined Anthracite Coal".We used the best quallity "Taixi anthracite coal" as raw materials through high temperature calcined at over 2000 by the DC electric calcined with results in eliminating the moisture and volatile matter from anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation. It has good characteristics with low ash, low resistvity, low sulphur, high carbon and high desity. It is the best material for high quality carbon products.It is the best material for high quality carbon products, it is used as carbon additive in steel industry or fuel.
