Preparation of Perovskite-type Oxides with Large Surface Area by Citrate Process

Abstract
Well-crystallized perovskite-type oxides could be synthesized at temperatures as low as 550–650 °C by the calcination of amorphous citrate complex precursors. The large specific surface areas of the oxides obtained suggest that the citrate process is very promising for preparing perovskite-type oxide catalysts for practical use.
