The lead nickelate niobate(PNN)-lead zincate niobate(PZN)-lead zirconnate titanate(PZT) piezoelectric ceramics were prepared by the solid-synthesis with the solid oxides as raw materials.The effect of the mico-addition of Na2O on the sintering process parameters and the piezoelectricity of the PNN-PZN-PZT ceramics were investigated.The results showed that the addition of Na2O was strict with the forming process of the PNN-PZN-PZT ceramics,otherwise,the segregation of chemical composition appeared in the sin...
