Title:
MANUFACTURING METHOD FOR STRONTIUM TITANATE FINE PARTICLES, AND STRONTIUM TITANATE FINE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2015/122181
Kind Code:
A1
Abstract:
[Problem] To provide: a manufacturing method for strontium titanate fine particles which enables the high yield manufacture of strontium titanate fine particles having a controlled shape; and strontium titanate fine particles. [Solution] A manufacturing method for strontium titanate fine particles comprising: step A1, in which an Sr-containing aqueous solution and a Ti-containing aqueous solution are prepared; step B1, in which the Sr-containing aqueous solution and the Ti-containing aqueous solution are mixed to prepare a mixed solution; step C1, in which a basic compound is added to the mixed solution to adjust the mixed solution so as to be basic, and a reaction solution is prepared; a step D1, in which the reaction solution is subjected to a sub-critical or super-critical reaction; and a step E1, in which, prior to the implementation of step D1, an amphipathic compound, which has a carboxyl group, and an organic basic compound, which does not contain a metallic element, are added to the Sr-containing aqueous solution, the Ti-containing aqueous solution, the mixed solution, or the reaction solution. The pH of the reaction solution used in step D1 is greater than 10.
