The solid-state reaction of ZrO2 and TiO2 from 1380°to 1530°C and its kinetics were investigated. The reaction rate was determined from X-ray diffraction intensities of the strongest peaks of the reactants and product ZrTiO4. The marker experiment indicates that diffusion of Ti4+ or O2- through ZrTiO4 controls the reaction rate. The activation energy for the formation of ZrTiO4 was about 45∼57kcal/mole. The effects of the minor component added and atmosphere on the reaction rate of ZrTiO4 formation were also discussed.
