Lead manganate antimonate doped niobium nickel-lead zirconate titanate piezoelectric ceramic
The invention discloses a lead manganate antimonate (PMS) doped niobium nickel-lead zirconate titanate piezoelectric ceramic (PNN-PZT) having the raw material formula: (1-x)Pb(Ni[1/3]Nb[2/3])[0.5]Zr[y]Ti[0.5-y]O[3]-xPb(Mn[1/3]Sb[2/3])O[3], wherein in the formula, x and y represent the molar content and have numerical values respectively being x=0.0-0.06 and y=0.10-0.20. A traditional solid phase synthesis process is adopted, a pre-sintering temperature is 800-900 DEG C, a sintering temperature is 1000-1300 DEG C, and a novel piezoelectric ceramic material is obtained, wherein the material has high piezoelectric coefficient (d33<*>=1000 pm/V) and excellent mechanical properties (E=120 GPa, and K1C=1.44 Mpa.m<1/2>). The piezoelectric ceramic based on lead zirconate titanate has high piezoelectric coefficient and excellent mechanical properties. The novel piezoelectric ceramic is mainly used in the fields of micrometric displacement actuators, piezoelectric sensors, transducers and the like, and has great market values.
