METHOD OF PRODUCING NANODISPERSED OXIDE MATERIALS IN FORM OF SPHERICAL AGGREGATES Russian patent published in 2017 - IPC C01G1/02 B82B3/00 C01B13/18 

FIELD: chemistry.

SUBSTANCE: method of producing nanodispersed oxide materials in the form of spherical aggregates is described, comprising preparing of a solution which contains soluble salts comprising cations and metal anions, followed by immersion of organic matrix for trapping the metal ions from the solution, wherein a solid ion-exchange resin is used as the organic matrix, containing an acrylic-divinylbenzene or styrene-divinylbenzene matrix, preliminary soaked in distilled water, which is placed into the solution with constant stirring until complete sorption of metal ions, the resulting sample of metal oxide precursor is extracted from the solution and dried, afterwards, the polymeric organic matrix is removed by a stepped heat treatment.

EFFECT: obtaining of simple or mixed metal oxides in nanodispersed state with narrow particle size distribution.
