Manufacture of composite metallic compound

Abstract

Abstract PURPOSE:To obtain a brittle-like composite decomposition product easy to pulverize in a simple stage by adding a metallic salt to an alkoxide of other metal, preparing a viscous melt of a low grade polymer, and thermally decomposing the melt. CONSTITUTION:To a single metallic alkoxide of Al or the like or a composite metallic alkoxide is added >=1 kind of salt of other metal such as ZrCl4 using a solvent or the like. By heating them, the solvent is removed, and polymn. is allowed to proceed to prepare a viscous melt of a low-grade metallic alkoxide polymer. By further heating the melt, thermal decomposition is caused to form a brittle-like decomposition product by volume increase. The product is optionally held under reduced pressure. The product is amorphous, and by pulverizing and roasting it, fine powder of a high purity crystalline composite oxide such as alumina-zirconia is obtd.
