Paper Abstract

Existing in pyroelectric crystals an electric polarization is compensated until the surface charge associated with the polarization is neutralized. Changing of crystal temperature causes the polarization change, what results in the free electric charge production. The temperature dependence of spontaneous polarization is called pyroelectric effect. In this paper some perovskite type pyroelectric ceramic materials based on lead zirconate and lead titanate are described and our own investigations concerning the lead lanthanum zirconate titanate PLZT pyroelectric compositions are presented.
