摘　　要：主要研究了(NaBi)0.5TiO3-NaNbO3-BaTiO3三元系无铅压电材料的介电、压电性能。随着第三种材料BaTiO3引入量的增加,三元系材料的介电常数和损耗均出现增大的现象。当n(Ba2+)=0.02mol时,三元系材料的压电常数d33、机电耦合系数kt值都达到最大值100pC/N和0.41。Dielectric and piezoelectric properties of (NaBi) 05 TiO3NaNbO3BaTiO3 leadfree ternary systems are discussed in this paper. When molamount of Ba2+ introducing to A site is added, the piezoelectric constant and loss are increased, which be like the instance of the (NaBi)05 TiO3BaTiO3 binary systems. As Ba2+=002mol, the d33 and Kt value achieve the maximal values 100 pC/N and 041 respectively. 
