SYNTHESIS OF NANOPARTICLES OF COMPOSITE METAL OXIDES IN SUPERCRITICAL WATER Russian patent published in 2012 - IPC C01G1/02 B82B1/00 C01D15/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical engineering. In order to obtain nanoparticles of complex oxide LiMeO₂, where Me denotes Co, Ni, Zn, Cu, 0.1 M aqueous lithium nitrate solution LiNO₃ and a salt of Me - Co, Ni, Zn, Cu are mixed with supercritical water in a flow reactor at temperature 370-390°C and pressure 220-230 atm. The metal salts used are such salts as cobalt sulphate CoSO₄, zinc sulphate ZnSO₄, nickel acetate Ni(CH₃COO)₂ and copper acetate Cu(CH₃COO)₂.

EFFECT: invention enables to synthesise nanoparticles of complex metal oxides using environmentally safe non-waste technology.
