ABSTRACT
A composite powder of ZrO2 dispersed in MgO was formed by a sol-gel method and morphological changes of the ZrO2 particles were studied as the composite powder was calcined. The composite was then sintered at 1450°C and examined by scanning and transmission electron microscopy. The distribution of ZrO2 particles in the composite formed by the sol-gel method was much better than in the case of composites formed by ball milling or coprecipitation. A nanocomposite was formed by the sol-gel method.
