Pb 0.95 Sr 0.05 )[(Ni 1/2 W 1/2 ) 0.02 (Mn 1/3 Sb 2/3 )0.06 (Zr X Ti Y ) 0.92 ]O 3 piezoelectric ceramics (abbreviated as PNW-PMS-PZT) with 1%mol excess PbO, 0.25 wt% CeO 2 and 0.2 wt% MnO 2 were prepared by traditional ceramics process. The phase structure of ceramics sintered at 1150°C were analyzed. Results show that the pure perovskite phase was in all ceramics specimens, the phase structure of PNW-PMS-PZT piezoelectric ceramics was transformed from tetragonal to rhombohedral, with Zr/Ti ratio increased in system; Effect of Zr/Ti ratio on piezoelectric and dielectric properties was investigated. Results show that ɛ r , tanδ, k p and d 33 increased with an increase of Zr/Ti ratio and reached the maximum values at Zr/Ti ratio of 50/50, then decreased with further increase of Zr/Ti ratio, whereas the variation of Q m with an increase of Zr/Ti ratio showed the opposite trend, T c showed a tendency to decrease with an increase of Zr/Ti ratio. The piezoelectric ceramics with Zr/Ti ratio of 50/50 was applied in high-power multilayer piezoelectric transformer, and properties parameter were ɛ r = 2100, tanδ=0.006, k p =0.613, Q m =1300, d 33 =380pC/N, T c =205°C.

The novel temperature-stable X8R dielectric materials could be sintered at 1180uC by doping Pb(Ti,Sn)O 3 additives into the BaTiO 3 ceramics, with a dielectric constant greater than 1550 at 25uC, dielectric loss lower than 2?0% and temperature coefficient of capacitance less than ¡15% from 255 to 180uC. The effects of Pb(Ti,Sn)O 3 additives and sintered temperature were discussed. Pb(Ti,Sn)O 3 can not only enhance the dielectric constant , but also improve the temperature stability of the BaTiO 3 ceramics effectively. The enhancement of Ti 4z 's polarisation and the smaller thickness of average grain shell resulted in increase in the dielectric constant. Sintered at a higher temperature, the temperature-capacitance curve was flattened. The decrease in the volume ratio of grain core to grain shell was helpful to improve the temperature stability.
