Abstract

Tetragonal ZrO2 has been prepared by decomposing zirconium citrate. Thermal decomposition of zirconium citrate has been studied using TG, DTA and DTG techniques. The powder X-ray diffraction studies showed that ZrO2 prepared by this method is tetragonal up to 600 °C after which it progressively transforms to the monoclinic phase. Beyond 800 °C the phase is completely monoclinic. This is related to the fine particles and small crystallites obtained. The formation of metastable tetragonal ZrO2 and its transformation to the stable monoclinic phase is studied as a function of temperature
