Abstract

The invention discloses a piezoelectric ceramic piece for a high-temperature laminated piezoelectric actuator and a preparation method of the piezoelectric ceramic piece, and belongs to piezoelectric ceramic pieces and preparation methods of the piezoelectric ceramic pieces. The composition chemical formula of the piezoelectric ceramic material provided by the invention is Pb < 0.97 > Sr < 0.03 > (Sb < 1/3 > Nb < 2/3 >) < 0.3 > (Ni < 1/3 > Nb < 2/3 >) < 0.7 > O < 3 + 2 > wt% Li2CO3 < 3 + 0.1 wt% CuO < 3 + 0.5 wt% Bi2O3 < 0.5 wt% > Li2CO3 < 3 + 0.5 wt% >, the preparation method provided by the invention comprises the following steps: mixing the raw materials according to the chemical formula, and then carrying out ball milling, drying, pre-sintering, secondary ball milling, drying, compression molding, sintering, silver paste printing, silver sintering and polarization. According to the piezoelectric ceramic piece, the sintering temperature is reduced while the piezoelectric property is excellent, volatilization of PbO is reduced, the piezoelectric ceramic piece has large deformation displacement and good stability, and the use requirement of a high-temperature laminated piezoelectric actuator can be met.
