FIELD: electricity.
SUBSTANCE: method includes formation of porous structure by annealing powder of lanthanum strontium manganite at synthesis temperature not less than 1300°C. At first annealing of lanthanum strontium manganite is carried out at temperature of 1100°C and 1200°C in the air with isothermal exposure of 14 and 10 hours respectively, then the produced powder is pressed using 1% solution of polybutyl methacrylate in acetone as a binder in quantity of 0.2 ml per 5 g of powder, final synthesis is carried out at temperature of 1450°C in the air during 10 hours. Usage of pore agent is not envisaged in the claimed method.
EFFECT: produced oxides have approximately the same porosity.
