Manufacture of solid solution of metallic oxide

Abstract

Abstract PURPOSE:To economically manufacture a fine-grained solid soln. of a metallic oxide of high purity having a uniform composition by reacting a barium or strontium salt with a titanium or zirconium alkoxide, alkali metallic ions and water. CONSTITUTION:A barium or strontium salt (A) such as barium oxalate is mixed with a titanium or zirconium alkoxide (B) such as titanium isopropoxide and an alkali metal (C) such as Na or K preferably in an org. solvent such as benzene, and the mixture is reacted at about 40-100 deg.C. The alkali metal (C) may be used in the form of its alcoholate. Decarbonated distilled water is added to the reaction product, and the formed white precipitate is taken out and dried at about 120 deg.C in air to obtain a solid soln. of a metallic oxide represented by the formula (where 0<=x, y<=1 and n>=0).
