Abstract. The article is a study of dielectric and piezoelectric properties of six compositions of PZT-ceramics with an addition of Pb(Mn1/3Nb2/3)O3. In the case of concentration of the additive of 0.05 mol, the dielectric and piezoelectric parameters are as follows: εr=875, QM=2030, tanδ =0.34%, Kp=0.45, d31=90×10-12CN-1. Within the temperature interval from -30°C to 50°C, the frequency independent parameterNr changes by about 0.6%.
