The invention relates to bismuth titanate natrium-silver-barium series piezoelectric ceramics with ABO3 structure. The general equation of the compound is [Bi0.5(Na1-xAgx)0.5] 1-yBayTiO3+aM alpha O beta (wt%), and in the equation, 0 alpha Obeta is one or plural doping oxide. The main constituent is 0-5 of Biw(Na1-x-y-zKxLiyAgz)1-wTiO3, M could be Na, K, Li, Ni, Zn, Cr, Co, Nb, Ta, Al, Cu, Fe, Ce, Pr, Nd, Sm, Gd, Dy, Er, Yb, In, Y, Sc, La, Ho, Lu, Sn, Sb, Mn, Ca, Ba, Sr, Mg, Si, Bi, Ag, etc. Alpha and beta mean the M element and atomicity corresponding to the relative oxide. The sintering temperature is 1100-1200 degree centigrade, keeping for 1-4 hours. The optimal value of the compound of d33 could be over 160pC/N, kp could be over 31%, dielectric loss could be below 0.03. And the technology is stable, and it would be made from traditional technology and raw material.
