METHOD OF PRODUCING LANTHANUM-STRONTIUM MANGANITE Russian patent published in 1994 - IPC

FIELD: production of electrodes for high-temperature electrochemical devices. SUBSTANCE: 0.5 M solution of manganese acetate ( its quantity being 22.6 ml ) is mixed with 0.5 M solution of lanthanum acetate ( its quantity being 13.3 ml ) and with 0.5 M solution of strontium acetate ( its quality is 9.0 ml ). 0.5 M solution of ammonia carbonate ( its quantity being 400 ml ) and 60 ml of hydrogen peroxide are added at pH 9.0. Thus prepared precipitate is sustained within 12 h and filtered. Then washing by distilled water and drying at 105 C within 6 h are carried out. Heat treatment at 1000 C is carried out within 2 h. EFFECT: decreases energy expense. 1 tbl
