| titleOfInvention | Method of obtaining nanodispersed manganites of rare-earth metals |
| abstract | FIELD: chemistry. ^ SUBSTANCE: invention can be used in production of magnetoresistors, materials or making magnetic recording heads and catalysts. An aqueous solution of a manganese salt and a rare-earth metal salt are prepared. A manganese compound is extracted from the obtained solution using a benzene solution containing trioctylamine, and the rare-earth metal compound is extracted using a benzene solution containing dipyridyl and acetyl acetone. The organic phases separated from the aqueous phases are mixed. An organic solvent is distilled at high temperature, after which the end product undergoes pyrolysis at 600-700 C. ^ EFFECT: invention cuts on synthesis time and enables to obtain nanodispersed manganites of rare-earth metals with particle size of 20-100 nm and output of not less than 93%. ^ 9 cl, 4 ex |
