Thermoanalytical investigations on hydrous zirconia

Article abstract of DOI:10.1007/BF01913925

The variations in the thermoanalytical curves for three differently produced powders of hydrous zirconia are discussed in connection with X-ray measurements and powder-metallurgical characterization. They were shown to characterize ZrO₂-H₂O bonding and the thermal treatment for the calcination of hydrous zirconia. They allowed selection of the product with the most favorable microstructure for a high sinter activity, an explanation of the phase formation and phase transformations, and estimations of energy content of the amorphous material and the thermal stability of the tetragonal phase. It was shown that thermal analysis is an appropriate method for the optimizing of ZrO₂-powder production.
