FIELD: inorganic chemistry, chemical technology. SUBSTANCE: invention relates to synthesis of manganese inorganic compounds used as catalysts, magnetoresistors and so on. A mixture of parent compounds of manganese and metals is homogenized, treated with volatile acid, for example, nitric acid to obtain a mixture of volatile acid salts. Then thermal treatment is carried out in a mixture of air and steam flow at 500-900 C under partial steam pressure 0.2-1 atm. Metal manganite of high purity is obtained at relatively low temperature. EFFECT: improved method of synthesis, high purity of product. 2 cl
