本文采用胶体－超临界流体干燥法制备纳米级ＺｒＯ２超细粉料，用透射电镜（ＴＥＭ）、比表面积（ＢＥＴ）和粒度分析法对颗粒尺寸进行观察和测定，并详细考察了制备条件对产品粒子粒度及其分布的影响
In this paper, nanocrystalline ZrO2 ultrafine powder was prepared by colloidal-supercritical fluid drying method. The particle size was observed and measured by transmission electron microscopy (TEM), specific surface area (BET) and particle size analysis. The effects of preparation conditions on the product Effect of particle size and distribution
