摘要：

The inverse microemulsion technique has successfully been used to synthesize lanthanum and nickel oxalate particles, which could readily be processed to form a fine LaNiO3 powder. Under appropriate conditions, the metal oxalate coprecipitates were microhomogeneously mixed in the form of spherical particles about 20 nm in diameter. When these coprecipitated lanthanum and nickel oxalate particles were clacined at 800-degrees-C for 20 h, fine LaNiO3 powder was obtained. This powder was found to have the formula LaNiO2.82-2.90.
