Internal friction Q-1 and Young's modulus E were measured as functions of temperature for undoped Pb(Zr0.65Ti0.35)O3 ceramics obtained by the sol-gel technique. Experiments were performed with a RAK-3 resonant mechanical spectrometer. The E(T) curves show two anomalies associated with two peaks, PR and PF, in the Q-1(T) dependence. Moreover, Q-1(T) curves recorded for two different frequencies show that the PR peak has a relaxation character. It was found that its activation energy and relaxation time should be attributed to the interaction of domains with point defects.
