METHOD USED FOR PRODUCTION OF THE METAL OXIDES POWDERS Russian patent published in 2008 - IPC C01B13/18 

FIELD: chemical industry; other industries; methods of production of the metal oxides powders.

SUBSTANCE: the invention is pertaining to production of the metal oxides powders and may be used in the chemical industry at production of the powders of the metals oxides. The method of production of the finely dispersed powders of the metals oxides includes preparation of the mixture containing the water solution, the melt or the water suspension of the salt of at least one metal, demonstrating the oxidative properties, and organic reducing agent. The obtained mixture is homogenized and heated up at its continuous feeding on the hot surface of the rotating heater. Then the evaporation and inflammation of the mixture is exercised. The released gaseous substances and the formed solid final product are continuously removed from the surface of the heater. The invention allows to receive the finely dispersed powders of the metals oxides in the continuous mode with the high specific productivity and to exclude the pulsing release of the gases.

EFFECT: the invention ensures production of the finely dispersed powders of the metals oxides in the continuous mode with the high specific productivity at exclusion of the pulsing release of the gases.
