Na 0.5 Bi 0.5 ) 0.93 Ba 0.07 TiO 3 ceramics with added 0-0.8 wt.% CoO were prepared by a citrate method and the influence of the CoO additive on the structure and electrical properties of the ceramics was investigated. All the specimens maintained a rhombohedral-tetragonal phase coexistence in cryst
Lead-free piezoelectric ceramics (1x)(0.98K 0.5 Na 0.5 NbO 3 -0.02LiTaO 3 )-x(0.96Bi 0.5 Na 0.5 TiO 3 -0.04BaTiO 3 ) (KNN-LT-BNT-BT) with x = 0-0.10 have been synthesized by a conventional sintering technique. All samples possess pure perovskite structure, showing room temperature symmetries of orth
