【 摘 要 】

Thermodynamics is investigated, and the optimum temperature and time modes of carbonization of a briquetted silica fume batch- brown coal semi coke are defined. The complete carbonization of the batch in the conditions of heat treatment is achieved at a temperature of 1923 - 1973 K within 15 - 20 minutes. The conditions and indicators of the chemical enrichment of carbonization products are established. After enrichment, the carbide content is more than 90%. Silicon carbide micro-powder is obtained with a specific surface area 8000 - 9000 m2/kg.
