Abstract

Perovskite-type LaFeO3 fine particles, prepared by a sol-gel method from an aqueous solution of nitrates, were dispersed in a dilute solution of water glass. The LaFeO3 catalyst was obtained by drying the suspension. The rate of LaFeO3 crystallite growth during thermal treatment was measured, and it was found that the fine particles suspended by water glass showed a highly inhabitory action against the crystallite growth of face (121).
