Effect of Pb(Ni1/2W1/2)O3on the Phase Transition Behavior of PbZrO3Ceramic

Solid solution of (1−x)PbZrO3−xPb(Ni1/2W1/2)O3;(1−x)PZ-xPNW ceramics, where x = 0.02-0.10, were prepared by solid state reaction. Dense (1−x)PZ – xPNW ceramics were obtained by sintering at 1,100°C for 4 h. Effect of PNW on crystal structure, phase transitions and thermal and electrical properties was investigated using X-ray diffraction, dielectric spectroscopy, hysteresis measurement and differential scanning calorimetry. The results indicated that the solubility limit of the (1−x)PZ–xPNW system was found at x = 0.04. It was proved that the intermediate phase is an antiferroelectric in the PZ-PNW system. Stability of the AFE intermediate phase was seen to improve with increasing PNW content.
