Apr 1, 2022The high-carbon product is obtained by the destructive distillation of coal. Carbon content in coke is very high thus it is called to be an almost pure form of carbon. It is greyish-black in color and is a hard, porous solid. It is used as a reducing agent in the extraction of minerals, manufacturing of steel and is also used as a fuel.
