摘要

In situ x-ray diffraction was used to optimize the synthesis of Aurivillius structure ceramic powders. Powders were prepared via conventional solid-state synthesis and the Pechini polymer precursor method. The phases Bi_4Ti_3O_(12), and Bi_2Sr_2NB_2TiO_(12) were studied. The Bi_4Ti_3O_(12) phase formed easily, regardless of processing route, between 400-500℃ and phase purity was achieved by 700℃ when using the Pechini method and by 900℃ with the solid-state method. The Bi_2Sr_2Nb_2TiO_(12) phase formation was strongly dependent on processing route. Achieving phase purity via solid-state synthesis required over 100 hours of heat treatment time at elevated temperatures. In contrast, phase purity was achieved after about 2 hours at 900℃ when using the Pechini method.
