The ferroelectric phase transition temperature T_c was measured for a ceramic sample of(Pb_0.97Sr_0.03)Zr_0.51Ti_0.490_3+2 wt% Nb_20_5+0.45 wt% Mn0_2. under pressure in the range from 10 kbar to 55 kbar. The pressure was generated in a pyrophyllite cell inserted in a tetra-hedral multianvil apparatus. The transition temperature was determined from the anomaly in the dielectric constant. The initial rate of change with pressure of T_c was 3.1℃/kbar. At 37kbar and 250℃, there was a break in the curve of T_c versus pressure and the slope suddenly changed to 7.5℃/kbar. It was supposed that this point was a triple point and a new paraelectric phase existed in the high pressure and high temperature region.
