Barium zirconate titanate Ba(ZryTi1-y)O-3 (BZT, y = 0.2, 0.25, 0.30, 0.35) ceramics have been prepared by a sol-gel process. The temperature dependence of dielectric permittivity of the ceramics has been investigated. The results show that the phase transition temperature T-C (or T-m) is suppressed...
