Abstract
The $0.65Pb(Mg_{1/3}Ta_{2/3})O_3-0.35PbTiO_3$ (PMT-PT)ceramics were near morphotropic phase boundary. The dielectric constant, the loss, and pyroelectric coefficient of the ceramics were measured as a function of temperature ($25^{\circ}C\;{\sim}\;250^{\circ}C$). The dielectric constant, the loss, and the pyroelectric coefficient could be improved with the addition of small amounts of $ZrO_2$ up to 0.2 mol%. The dielectric and pyroelectric peak temperature are slightly shifted to lower temperatrues with the addition of amount of $ZrO_2$.
