Abstract

Fine SiC powders were obtained by heating SiO₂-C mixed powders synthesized by spraying a mixture of silicon tetrachloride and heavy oil into air-propane flame. By analyzing the properties of the SiC powders, it was found that agglomeration factor (Stokes diameter/BET diameter) can evaluate the degree of agglomeration, and SiC powders which had a low agglomeration factor exhibit a high green density and high sintered density.
