摘要：

Ultrafine 14 nm 3 mol% Y2O3 stabilized tetragonal ZrO2 powder was prepared by emulsion processing. The obtained particles were weakly agglomerated into polyhedral or spherical shaped powders. The powder characteristics were investigated by using X-ray diffraction (XRD), X-ray fluoroescence (XRF), inductively coupled plasma spectroscopy (lCP), nitrogen adsorption (BET model) and thermal analysis (DTA-TG). The experiments indicated that the heterogenous distillation used in the process was an effective method to remove residual water in the gel-precipitate and reduce the formation of strong agglomerates. The powder presented good formability and sinterability.
