PROCESS FOR PRODUCING PEROVSKITE COMPOUND POWDER

A process for producing a perovskite compound powder, characterized by comprising the first step of preparing an agglomerated perovskite compound represented by general formula ABO3 wherein A is at least one group A element selected from among Mg, Ca, Sr, Ba, and Pb and B is at least one group B element selected from among Ti, Zr, Hf, and Sn, and the second step of disintegrating the agglomerated perovskite compound prepared in the first step by heating at a temperature in the range of 30 to 500°C in a solvent. This production process can eliminate the need to utilize conventional mechanical disintegration means orimpact by a grinding medium or an air stream for the disintegration of the agglomerated perovskite compound, and can provide a perovskite compound powder that does not cause contamination of the disintegrated product with impurities from the grinding medium, is highly pure, does not contain chipping particles and has a narrow particle size distribution.
