Heat Treatment During Preparation of Nano-zirconia Powders by the Liquid-phase Process
|
Abstract:
Nano-ZrO2 powders were prepared by the modified precipitate method under various heating treatment conditions. TEM, SAXS, BET and XRD analyses indicated that the influence of heat treatment on the performance of nano-ZrO2 is notable. Combining the experimental results and theoretical analysis, the mechanism of particles?growth and aggregation, and the effect of heat treatment upon the change of composition, granularity and microstructure were proposed.
