Determination of the Grain-Size Distribution of Zirconia Based Powders by the Methods of Static Laser Scattering and Optical Microscopy
Abstract
Dispergation conditions of zirconia doped with 3 % mol yttrium oxide are specified. Grain-size distribution of the power particles is determined using static laser scattering and optical microscopy. Electrophoresis with titration is used for measuring the dependence of zeta-potential of zirconia suspension on öl value. The effect of the acidity on the stability of suspension during measurement is considered. It is shown that stable suspension can be obtained by shifting pH value of dispersion media both to acidic or alkali regions and also by adding surface active substances (e.g., Dolapix CE 64).
