A-Tris(hydroxymethyl) aminomethano-{ditris(hydromethyl)aminomethanolanthanum-ditris(hydroxymethyl)aminomethanocobalt} as precursor for lanthanum cobaltate obtaining

摘要

The invention relates to the chemistry of heteronuclear coordinative compounds. Summary of the invention consists in that it is proposed A-[tris(hydroxymethyl)aminomethano]-{di[tris(hydroxymethyl)aminomethano] lanthanum-di[tris(hydroxymethyl)aminomethano]cobalt} of the formula: CHFORMas precursor for lanthanum cobaltate obtaining. The given complex, as a result of low-temperature pyrolysis and short-term high-temperature posttreatment, forms polycrystalline powder of lanthanum cobaltate LaCoO3. The compound may be used in radio electronics and chemical industry, where this double oxide is used in the capacity of catalyst.Claims: 1
