GCA Calcined Anthracite Coal is also called "Gas Calcined Anthracite Coal", as raw materials through high temperature calcined at over 2000 degrees by the DC electric calciner which 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.

Calcined Anthracite Coal has good characteristics with low ash, low resistivity, low carbon and high density.

Calcined Anthracite Coal is the best material for high quality carbon products, it is used as carbon additive in steel industry or fuel.
