Abstract

Lanthanum nickel oxide$(LaNiO_3)$ powders have been prepared via a mechanochemical processing without any additional heat treatment. When a mixed lanthanum and nickel oxide was mechanically activated for 6 hours with 450 rpm, a stable and single phase perovskite powder was successfully synthesized and its crystallite size of about 90 nm is calculated by using the Scherrer equation.
