Abstract
The invention provides a process for production of powder of perovskite compound which comprises: The process makes it unnecessary to resort to a conventional mechanical crushing means or to make use of impact caused by milling media or airflow, but it makes possible to obtain a powder of perovskite compound which is not contaminated with impurities derived from milling media or chipping particles but has a high purity and a narrow particle size distribution.
