Lomanova, N. A.; Morozov, M. I.; Ugolkov, V. L.; Gusarov, V. V.

A number of new Bi m 1Fe m−3TiO3 m 3 compounds with integer and fractional m values are identified in the Bi4Ti3O12-BiFeO3 system. All of the compounds are shown to have Aurivillius-type structures. The phase-transition and decomposition temperatures of the new and earlier known compounds of the Bi4Ti3O12-BiFeO3 system are determined. The linear thermal expansion coefficients of the synthesized compounds are evaluated using dilatometry, and their sintering onset temperatures are determined.
