Summary

Three methods of production of fine SiC powders are described: attrition, chemical vapor synthesis, and carbothermic reduction. Chemical cleaning of powders produced by these methods is necessary. The powders are characterized physically by measuring surface area, particle size, and morphology. Chemical characterization is accomplished by measuring total carbon, free carbon, total silicon, free silicon, and silica. Interchange of information between users and producers is necessary to make the manufacture of high-performance ceramics a real economic factor in the economy.
