| Abstract: | CaO stabilized ZrO 2 nanometer sized powders were prepared by Gel supercritical fluid drying (SCFD) method, and their structural properties and sinterability were studied. It was shown that the ultrafine powders had small particle size and high surface area, which led to high sinterability. And the content of CaO could make great influnce on the properties of ZrO 2 based powders. |
