Title:
INORGANIC FINE PARTICLES, INORGANIC RAW MATERIAL POWDER, AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2004/041427
Kind Code:
A1
Abstract:
A novel method for producing inorganic fine particles, which comprises heating a liquid raw material and applying a shock wave to the material. The method allows the suppression of mutual agglomeration or adhesion of particles in the pulverization of a liquid raw material, such as a slurry of zirconia hydrate particles, for preparing an inorganic raw material powder having a sharp particle size distribution and further allows, in the case of a multi-component system, the homogenization of the chemical composition among the resulting particles and even in the interior of a particle.
