Gelling Process of Ultrafine ZrO2 at Room Temperature


Article Preview

Gelcasting is widely used in ceramic material preparation. A disadvantage of this technology is inhomogeneous structure and inner stress caused by temperature gradient owing to the heating of slurry. Theoretical analysis and experiments prove that gelling process of ultrafine ZrO2 can be completed at room temperature. When premixed solution/initiator/catalyst ratio is 100/1/0.5 (by volume), the gelcasting ZrO2 body with homogeneous structure and bending strength of 50.09MPa is prepared.
