摘　　要：The effects of glass flit on the sintering and electric properties of PMN-PT textured ceramics were investigated. The glass frits, including PbO, Bi2O3 and ZnO, were selected since liquid phase sintering lowered the PMN-PT sintering temperature. The piezoelectric properties of PMN-PT ceramics with glass frit addition are strongly dependent on the densification. The addition of glass frits into PMN-PT matrix reduced the sintering temperature to 1 100℃ instead of 1 150 ℃ for samples without glass. The piezoelectric coefficients （d33） of PMN-PT textured ceramics achieved 568 pc/N with 1 wt% excess PbO.The effects of glass flit on the sintering and electric properties of PMN-PT textured ceramics were investigated.
