Abstract
PURPOSE: To prepare finely divided particles of high-purity ZrO2 in high yield, by adding an organic solvent to colloidal particles obtained by hydrolyzing an aqueous solution of water-soluble Zr salt, followed by hydration, drying, and heating.
CONSTITUTION: An aqueous solution of water-soluble zirconium nitrate or zirconium oxychloride having a ZrO2 concentration about 0.1W1mol% or an aqueous solution of the salt, and, if, necessary, at least one salt of Mg, Ca, or metallic elements having tri or more valence is boiled and hydrolyzed to form colloidal particles. An organic solvent, e.g., carbon tetrachloride, benzene, toluene, xylene, etc. is added to these particles, and water molecules which cause primary agglomeration of particles are removed by distillation under heating. The prepared amorphous hydrate of ZrO2 is heated, dried, and heated to 200W1,000°C, to prepare finely divided particles of ZrO2 which will not agglomerate substantially, having high bulk density.
