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.
- Super critical drying,
- Ultrafine particle,
- Zireonia
