ABSTRACT:
The invention relates to a method for obtaining artificial graphite powder for electrical engineering, manufacturing synthetic diamonds and in other fields of technology with especially high requirements for graphite purity. The novelty of the inventive method is the use of pyrolytic carbon material obtained by methane pyrolysis at a temperature of 2100-2400° C. Pyrolytic carbon obtained as a waste product of pyrolytic anisotropic material can be used as a carbon material. The method includes grinding carbon material and its graphitizing at a temperature of 2600° C.-2700° C. The inventive method simplifies the process of preparing artificial graphite powder and enhances the degree of graphitization, which improves the quality of the final product.
