Abstract
Zirconium hydroxide is a precursor material of zirconia. Variations in both chemical and physical properties of this precursor affect the properties of the final product. One of these variations is that of the pH of the liquid in contact with the final hydroxide precipitate. We show here, using advanced dynamic diffraction techniques, how pH affects the kinetic aspects of synthesis: In particular we investigate the effect of pH on the temperature of onset of crystallization, the rate of crystallization and crystal growth during calcination, as well as the temperature and rate of transformation, on cooling, of the tetragonal to monoclinic form of zirconia.
