Graphitization refers to the high temperature heat treatment process of transforming amorphous carbon into three-dimensional ordered planar hexagonal mesh laminated graphite by heating carbon products to 2300℃ or above in a high temperature electric furnace. The graphitization of carbon materials is carried out at a high temperature of 2300 ~ 3000℃. Because the combustion of fossil fuels is difficult to obtain such a high temperature, it can only be achieved by electric heating roasting in industry.
