FIELD: producing oxide systems. SUBSTANCE: method involves synthesis of hydroxo-containing compound. It is followed by thermolysis. Synthesis is carried out by treating intercalation compound ( having common formula given in specification ) by aqueous solution of alkali metal permanganate. Thus prepared solid phase is separated by filtration and washed by water. Its thermal decomposition takes place at 600 C. EFFECT: improves efficiency of the method. 1 tbl
