High-pressure synthesis of bismuth based perovskite (BiNaLi)TiO (BNLT) (=0.1, 0.15, 0.2, 0.25, 0.4, 0.5) was demonstrated. Single phase BNLTs with perovskite structure were successfully synthesized for 0.1 by the solid state reaction method. The solid phase reaction occurred in the pressure range of 6-10 GPa, and in the temperature range of 800-1200 C. Two thermal anomalies were observed in single phase perovskite BNLT (=0.1) as well as (Bi,Na)TiO. The cusp like anomaly at 210 C was assigned to a rhombohedral-tetragonal structural phase transition. The finished products of 0.2 included three kinds of impurities, which were affected by the selection of starting materials.
