Dielectric, Piezoelectric, and Pyroelectric Properties of Barium-Modified Lead Magnesium Tantalate-L
46stract Dielectric, piezoelectric and pyroelectric properties of relaxor ferroelectrics in the 0. 65Pbl..Ba, (Mg1,3Ta2,3)03-0, 35PbTi03 solid solution series have been investigated. The dielectric constant and loss of ceramic samples were determined. The piezoelectric d33 constant and electromechanical coupling factor were measured for various compositions in the Ba-doping PMT-PT ceramics, The pyroelectric coefficient and spontaneous polarization were measured by the static Byer-Roundy method as a function of temperature. The values of dielectric constant, electromechanical coupling factor and pyroelectric coefficient for Ba-doped PMT-PT are much larger compared to the values observed for the undoped PMT-PT ceramics. Ba-doping also shifted the Tc downward, approximately 6 ‘C/mol% additon of Ea. Further additions of Ba could be used to shift the Tc downward without significantly changing the dielectric behav i or.
