In this paper, the preparation of lanthanide chromium bimetallic alkoxide and perovskite LaCrO_3 powders by the metal alkoxide hydrolysis methods were invest.

Electrical Conductivity of Sr and Ti doped LaCrO_3 Ceramics;

The optimal processing parameters and conditions of passivation films on galvanized steel sheet treated with rare-earth cerium and lanthanum salts were obtained by orthogonal experimental method.

The effects of lanthanum salt-doping on the photocatalytic degradation of methylene blue in solution,phase structure and crystallite size of the TiO2 films were investigated.

The powders of calcium-doped lanthanum chromite were synthesized by the low temperaturecombustion methodusing organic precursor prepared by citric acid-nitrate system,and some process parameters were optimized by orthogonal experiment.

This paper introduces the preparation methods and application fields of the doped lanthanum chromite material, expounds its performance advantages and study trends in each application field, and analyzes its market prospect.

Lattice distorts and lattice parameters of lanthanum chromite decrease with increasing Sr content.
