| Abstract: | In this paper the surface-exfoliation phenomenon of bodies gelcasted in the air was eliminated by adding 2.6wt% of water-soluble polyacrylamide(PAM) to zirconia ceramic suspension.The performance of zirconia wet adobe with complex shape by gelcasting is good and dense.Also the dispersion characteristics of the zirconia powder in the water in the presence and without of PAM is investigated.Meanwhile the flexural strength and microstructure of bodies are measured and observed in detail. |
| Keywords: | gelcasting Zirconia flexural strength microstructure |
