Abstract
A new method, hydrothermal oxidation method, has been developed to prepare zirconia fine powders by reactions between Zr metal and high-temperature high-pressure water or solutions. Zr metal and water sealed in a Pt capsule reacted under 98 MPa above 250°C and produced monoclinic ZrO2 fine grains having the average crystallite size of 24 nm. Further heating of this product up to 1000°C yielded a dense sintered body of m-ZrO2 with the maximum relative density of 99.0%. The hydrothermal oxidation method has been applied to the preparation of stabilized zirconia powders using Ca or Y solutions instead of water. A partial stabilization has been achieved when an excess Zr was existed in the capsule to decompose the solutes and the solvents at higher temperatures.
