The invention relates to a low-temperature-sintered lead antimonate manganate-lead zirconate titanate piezoelectric ceramic with low dielectric loss and a preparation method thereof, belonging to the field of ferroelectric materials. The invention aims to solve the technical problems of high sintering temperature and low piezoelectric properties of existing hard ceramic. The chemical general formula of the low-temperature-sintered lead antimonate manganate-lead zirconate titanate piezoelectric ceramic with low dielectric loss is 0.05Pb(Mn<1/3>Sb<2/3>)O<3>-0.47PbZrO<3>-0.48PbTiO<3>+ x wt%Li<2>CO<3>, wherein x is greater than 0 and less than or equal to 1. The preparation method comprises the following steps: proportioning components according to the proportions of the ceramic components, then sequentially carrying out pre-sintering, tabletting and glue discharging, then performing sintering at 950 DEG C, and then carrying out silver sintering and polarization to obtain the low-temperature-sintered lead antimonate manganate-lead zirconate titanate piezoelectric ceramic with low dielectric loss. According to the invention, by introducing a proper amount of Li<2>CO<3>, the piezoelectric property of the produced ceramic is improved by 27-34%, and the sintering temperature of the ceramic is obviously reduced. The sintering temperature is about 950 DEG C, so requirements on a sintering furnace is greatly reduced, and meanwhile, energy cost is reduced.
