【Abstract】 SiC powders were synthesized with high boiling point organosilicon by pyrolysis process.It was proved by many experiments that the better β-SiC crystallization can be obtained at 1450℃,and keeping this temperature for 2 hours. Pt and FeSO 4 composite catalysts can effectively improve the ratio of ceramic inversions.更多还原
