摘要
The possibility of the substitution Bi -> Ln occurring in the Bi3TaTiO9 Aurivillius phases has been studied for the first time. The Bi2LaTaTiO9, Bi2NdTaTiO9, Bi2SmTaTiO9, and Bi2GdTaTiO9 compounds have been synthesized according to solid-phase reactions in the temperature range 800-1100A degrees C, and their unit cell parameters have been determined.
