The Effect of Particle Morphology and Particle Size Distribution on the Property of Slip Casting SiC

The 1.2µm and 100µm silicon carbide were prepared by the process of reshaping and classification. The effect of particle morphology and particle size distribution of silicon carbide on tap density, green body density and apparent viscosity of slurry were analysized. The result showed that the particle size distribution closed to normal distribution and the particle morphology closed to spherical were the main cause that leads to the lower apparent viscosity and the higher density of the green body.
