| Abstract: | The preparation technology of low-temperature sintering modified PbTiO 3 with a small amount of low-melting additives SiO 2 is investigated, and the advantageous technological parameters are obtained. This modified PT material, which has excellent properties such as low-sintering temperature, high piezoelectric activities, large piezoelectric anisotropy, high mechanical quality factor, can be used for multilayer piezoelectric ceramic filter and multilayer piezoelectric step-down transformer. |
