With the grinding time increasing from 1 h to 2 h, the slurry viscosity decreased dramatically from to Pa s. Further increase in the grinding time to 3 and 4 h resulted in quite slight decrease in the viscosity. Therefore, we chose 3 h as the optimal grinding time for the preparation of 3YTZP ceramic slurry through threeroller mill.
