Elastic modulus(Young's modulus M and shear modulus G)and internal friction Q^<-1> are measured as a function of temperature from -180℃ to 500℃ in undoped lead zirconate titanate(PZT)ferroelectric ceramics in the range of kHz and low frequencies(0.1 to 1 Hz). New phase transition temperatures at the morphotropic zone at low temperatures are determined from the elastic modulus minimum. Permittivity ε and dielectric loss tan(δ)are measured in the frequency range of 20Hz to 10kHz. Both mechanical and electrical measurements allow the observation of relaxation peaks in the ferroelectric phase. The Arrhenius plots of all these results show that it is possible to investigate these relaxation processes using both experimental techniques.
