| Abstract: | This study shows that the surface-exfoliation phenomenon of green bodies gelcasted in air was eliminated via adding 2.6wt% amount of water-soluble polymer polyacrylamide(PAM) to the monomer solution.It is favorable that performance of complex form shape green bodies of zirconia formed by gelcasting.It is evenly fine and close.The dispersion of ZrO2 powder in water in the presence and without of PAM was investigated.The flexural strength and microstructure of green bodies were measured and observed detailedly in this article. |
| Keywords: | Gelcasting Zirconia Flexural strength Microstructure |
