Abstract

Abstract: The pyroelectric effect in PZT and PT ceramics was measured. The structural change of the two materials with temperature was investigated by XRD method. The relationship between structure and pyroelectric effect was discussed. The experimental results exhibited that the pyroelectric effect is dependent on the change of cell parameters with temperature. The larger the change of axis c and c/a, the larger the pyroelectric coefficient.

Key words: PT, PZT, pyroelectricity, XRD
