Perovskite-type nanometer material and preparation method thereof
The invention relates to a perovskite-type nanometer material and a preparation method thereof. The preparation method comprises the steps of preparing a precursor of a nanometer (CaxNd1-x)0.1La0.9Co0.5Fe0.5O3(x=0.1-0.4) material from initial raw materials including Nd(NO3)3.6H2O, Ca(NO3)2.4H2O, La(NO3)3.6H2O, Co(NO3)3.6H2O and Fe(NO3)3.6H2O by using a coprecipitation method; and calcining the precursor to obtain the nanometer (CaxNd1-x) 0.1La0.9Co0.5Fe0.5O3(x=0.1-0.4) material. The preparation method disclosed by the invention has the advantages that the raw materials are available; the preparation method is simple and safe in step, free of large special equipment, small in investment and relatively low in production cost; and the product is short in production period, high in purity, stable in structure, resistant to chemical corrosion and relatively good in industrial application prospect.
