在Bi_4Ti_3O_（12）-BiFeO_3体系中发现了一系列新的Bim+1Fem-3Ti_3O_3m +3化合物，其m值为整数和分数。所有化合物均具有Aurivillius型结构。的相变和分解温度的新的和以前已知的化合物的Bi 4 Ti 3 O 12 BiFeO 3系统的测定。使用热膨胀仪评估合成的化合物的线性热膨胀系数，并测定其烧结起始温度。
A number of new Bim+1Fem-3 Ti3O3m+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 Bi4Ti3O12BiFeO3 system are determined. The linear thermal expansion coefficients of the synthesized compounds are evaluated using dilatometry, and their sintering onset temperatures are determined.
