Temperature coefficient of piezoelectric constants in Pb(Mg1/3 Nb2/3)O3 - PbTiO3 ceramics

Temperature coefficient of piezoelectric constants in Pb(Mg1/3 Nb2/3)O3 - PbTiO3 ceramics

In this work, the thermal stability of piezoelectric constants of PMN-PT ceramics in the tetragonal and rhombohedral phases were investigated in a wide range of temperatures. The results showed that the tetragonal PMN-PT presented higher thermal stability and, consequently, the temperature coefficie...
