Abstract
To assist the development of applications for multilayer piezoelectric devices, the low-temperature sintering piezoelectric ceramics of 0.3Pb(Zn 1/3 Nb 2/3 )O 3 -0.7Pb(Zr 0.49 Ti 0.51 )O 3 with Li 2 CO 3 and Sm 2 O 3 additives were fabricated by a conventional solid-state reaction, and their structural and piezoelectric properties were studied. With the addition of Li 2 CO 3 , the minimum sintering temperature of 0.3Pb(Zn 1/3 Nb 2/3 )O 3 -0.7Pb(Zr 0.49 Ti 0.51 )O 3 piezoelectric ceramics was reduced from 1125 °C to 950 °C through the formation of a liquid phase and its piezoelectric properties showed almost no degradation. When the sintering temperature was below 950 °C, however, the piezoelectric properties degraded obviously. The additional Sm 2 O 3 resulted in a significant improvement in the piezoelectric properties of 0.3Pb(Zn 1/3 Nb 2/3 )O 3 -0.7Pb(Zr 0.49 Ti 0.51 )O 3 ceramic with added Li 2 CO 3 . When sintered at 900 °C, the optimized properties of the 0.3Pb(Zn 1/3 Nb 2/3 )O 3 -0.7Pb(Zr 0.49 Ti 0.51 )O 3 piezoelectric ceramic with 0.3 wt% Li 2 CO 3 and 0.3 wt% Sm 2 O 3 were obtained as d 33 = 483 pC/N, k 31 = 0.376, Q m = 73, ɛ r = 2524, tan δ = 0.0178.
