Investigating the influences of processing parameters on the C/Si molar ratio of resulted nanosized SiC powders indicated that there was a direct pyrolytic reaction from DMS to SiC as well as the previous proposed two-step reaction. Under the optimized processing conditions, the silicon carbide powders of homogeneous particle size distribution, spherical shape and stoichiometrical C/Si molar ratio are obtained. The silicon carbide particle consists of β-SiC crystallite arranged randomly.

论文系统研究了工艺条件对产物粉体C／Si摩尔比、粉体颗粒尺寸和组成粉体的SiC微晶尺寸的影响；研究了粉体制备过程中可能发生的化学反应，提出了反应过程中除了分步进行的生成SiC的反应外，同时在高温区还存在一步完成的生成SiC的化学反应的观点；通过调整工艺参数，制备得到了粉体尺寸分布均匀、呈均匀球状、C／Si摩尔比符合化学计量比的颗粒尺寸为40nm的纳米SiC粉体。
