Two series of PT-type materials doped with Eu+3 with the formula PbxEuyTi0.98Mn0.02O3 (x = 0.98, 1.00 and y = 0.00, 0.02, 0.04, 0.08, 0.12) were prepared by conventional ceramic technique. The compounds with compensated and uncompensated valences were sintered between 1150 and 1220°C. The two types of compounds and the content of the donor ion, Eu+3, influence the mechanical and dielectric properties of sintered samples. The spectra and data obtained on 151Eu Mössbauer measurements are discussed.
