Effect of Surface Modification on Slip Casting of SiC Slurry

Article Preview

Abstract:

In this study,the Zeta potential of original and modified SiC micropowder was researched,and the effects of surface modification on SiC slurry solid loading,rheologyh and density of slip casting body were studied.The structure of body was looked through SEM. The results indicated that the dispersion of modified SiC micropowder was greatly improved,the slip casting SiC slurry which had 73vol% solid loading,low viscosity and good fluidity was prepared,after slip casting,the density of body was 2.698[g·cm-3],and the structure was uniform.
