Mechanisms for the formation of laminar titanates AIIn-4La4Tin-1O3n from coprecipitated component systems
The conditions and sequences of the phase transitions in the synthesis of laminar perovskite-like titanates A II n -4 La 4 Ti n -1 O 3 n (A II = Ca, Sr) from mixtures of coprecipitated components were determined. The mechanisms for formation of the laminar structure of these products were found to...
