ABSTRACT:
A method for manufacturing dielectric titanate fine powder having the formula Ba.sub.1-x Sr.sub.x TiO.sub.3 wherein 0<x<1 is disclosed, which includes the steps of preparing a hydrolysis product of an inorganic titanium compound TiO.sub.2.xH.sub.2 O by dissolving the inorganic titanium compound in a neutral or alkaline aqueous solution, reacting the hydrolysis product with a water soluble salt of Ba and a water soluble salt of Sr in an aqueous alkaline solution having a pH no less than 13.0 to thereby obtain the dielectric fine powder having the formula Ba.sub.1-x Sr.sub.x TiO.sub.3 wherein 0<x<1, and filtering the fine powder from the remaining solution.
