Abstract
A method for manufacturing strontium titanate microparticles with excellent dispersibility is provided, which can be manufactured under simple conditions. A method for producing strontium titanate microparticles having a reaction process in which an organic titanate ester and a strontium compound are reacted in the presence of a hydrazine or hydrazide compound, under conditions where the pH is 12 or higher, the reaction temperature is 150°C or higher and 250°C or lower, and the reaction time is 0.5 hours or higher and 2 hours or lower, wherein the molar ratio of the hydrazine or hydrazide compound to the organic titanate ester (hydrazine or hydrazide compound / organic titanate ester) is 10 to 75.
