Pb(Zr1-xTix)O3 ceramics were prepared using the traditional solid-state method.The temperature stability was enhanced by adjusting the zirconium titanium mole ratio to locate these materials within the tetragonal region, and the electrical properties were improved by optimizing the sintering temperature.Experimental results showed that the system entered the monotetragonal region when x=0.52, and the temperature stability of the ceramics was subsequently improved.Over the range from room temperature to 300 ℃, the d33 change rate was ±14.7%. The Pb(Zr0.48Ti0.52)O3 ceramics sintered at 1 250 ℃ exhibited optimal electrical properties: d33=183 pC/N, TC=402 ℃, and εr=1 209.
