METHOD OF PRODUCTION OF FILMS ON BASE OF SIMPLE OR COMPLEX OXIDES OR THEIR SOLID SOLUTIONS Russian patent published in 2007 - IPC C01B13/18 B05D5/12 

FIELD: production of film catalysts, magnetoresistors, fuel cells, magnetic information recording and storage head materials and sensors showing content of different gases.

SUBSTANCE: proposed method consists in production of water soluble salt or mixture of water soluble salts of volatile acid or volatile acids of respective metals, for example manganese chloride or mixture of yttrium, barium, iron and cobalt oxides. Mixture thus obtained is applied onto substrate and is dried at temperature of 100C. Then, substrate is heated to melting point of the most high-melting salt and is cooled to temperature below 500C, after which heat treatment is performed at this temperature in flow of mixture of air and steam and rate of delivery of 0.1-100 ml/min and partial pressure of steam not below 0.1 atm.

EFFECT: facilitated procedure; enhanced ecological safety; improved quality of films.
