| 摘 要： | 通过研究不同干燥条件下制得的二氧化锆的织构和结构，发现在超临界干燥过程中附加一定的惰性气体压力能够防止或大大减小凝胶在干燥过程中的收缩，从而可提高ＢＥＴ表面积，和普通空气中干燥得到的二氧化锆相比，超临界干燥得到的二氧化锆的孔结构大为改善。同时ＢＥＴ表面积地增大。

| Abstract: | Ultrafine ZrO2 with high BET surface area and large pore size, as compared with that dried in air, was prepared by Super Critical Drying. In Super Critical Drying process, application of inert gas pressure could eliminate or reduce the gel shrinkage, so that the surface area and pore volume of ZrO2 could be increased and its particle size and pore size could be decreased. |

| Keywords: | Super critical drying Ultrafine particle Zirconia |
