METHOD OF PRODUCING COMPLEX METAL OXIDES Russian patent published in 2025 - IPC B22F9/24 B22F9/30 C01G1/02 

FIELD: chemistry.

SUBSTANCE: invention relates to synthesis of powdered inorganic materials – composite metal oxides and oxides and can be used to produce inorganic materials, namely composite metal oxide powder used to produce functional ceramics and coatings. Method involves using, as initial substances, soluble thermally unstable metal salts included in the complex oxide in proportions corresponding to the composition of the complex oxide, and a soluble organic component to obtain a joint solution thereof. Solvent is removed from the obtained solution to obtain a film and is subjected to thermal action, as a result of which there is initiation and implementation of the process of its combustion and synthesis of the composite metal oxide powder. Film is mixed with the prepared compound oxide powder of the same composition to obtain composition containing 10-50 wt.% of said powder.

EFFECT: enabling reduction of energy intensity and time for initiation of combustion, reduction of emission of harmful gaseous substances during combustion and synthesis.
