The Preparation of ZrO₂ and the Influence of the Calcination Temperature

Abstract:

nanoZrO₂ ceramic powders have excellent properties in many field. In order to obtain nanoZrO₂ powder with excellent properties, the study of preparation methods become a hotspot. The nanoZrO₂ powders new preparation technology from cheap raw materials is target of this paper. nanoZrO₂ powers were preparated from ZrOCl₂ and NaCO₃ as raw material. The optimum technology parameters were determined as follow, namely at 40°C, C (_ZrOCl2) =0.4mol/L, C (_NaCO3) =1.0mol/L, 2% the surface activity agent. nanoZrO₂ powders preparated were characterized by XRD, TEM and Electron Diffraction . The results show that the ZrO₂ powders prepared are crystal and the sizes are nanometer. The ZrO₂ average sizes were calculated with the scherrer formula. The nanoZrO₂ sizes change with temperature was discussed. The result is ageerment with that calculated with the scherrer formula.
