| 摘 要： | Nanncrystalline ZrO2 particulates with different sizes were prepared by precipitation method using ethanol as dispersive and protective reagent. XRD patterns show that the synthesized ZrO2 is monnclinic in structure with space group P21/a when calcination temperature is in the range of 400- 1000 ℃ . It is found that the smaller the particle, the bigger the crystal lattice distortion, the worse the costal growth, and the lower the diffrnction intensity. TEM images reveal that ZrO2 particles are spherical in shape, and the particle size distribution is in narrow range. The mean sizes of the particles increase with the increase of calcination temperatures . It is first to observe tbe streaks of different crystallographic planes. Thermogravimetric analysis indicates that the crystallization temperature of ZrO2 is 461.32 ℃ . Measurement of ZrO2 relative density shows that the relative density of nanocrystalline ZrO2 powders increases witb the increasing of ZrO2 particle sizes.

| Abstract: | Nanocrystalline ZrO2 particulates with different sizes were prepared by precipitation method using ethanol as dispersive and protective reagent. XRD patterns show that the synthesized ZrO2 is monoclinic in structure with space group P21/a when calcination temperature is in the range of 400–1000°C. It is found that the smaller the particle, the bigger the crystal lattice distortion, the worse the crystal growth, and the lower the diffraction intensity. TEM images reveal that ZrO2 particles are spherical in shape, and the particle size distribution is in, narrow range. The mean sizes of the particles increase with the increase of calcination temperatures. It is first to observe the streaks of different crystallographic planes. Thermogravimetric analysis indicates that the crystallization temperature of ZrO2 is 461.32°C. Measurement of ZrO2 relative density shows that the relative density of nanocrystalline ZrO2 powders increases with the increasing of ZrO2 particle sizes.
