Abstract
Dielectric, piezoelectric and pyroelectric properties of seven PZT-ceramics compositions are investigated. They were modified by adding Pb(Mn1/3Sb2/3)O3 and part of Pb2+ ions have been substituted for Sr2+. Additive concentrations have been varied from 1 to 7 mol%. In that concentration range it has equivocal effect which is typical for donor or acceptor admixtures.
