摘　　要：用静态法对不同制备工艺和不同PZT掺杂量的(1-x)PST-xPZT陶瓷的热释电系数进行了测试,发现随着PZT掺入量的增加逐渐降低PSTZT陶瓷的热释电系数.采用两步法工艺制备的PSTZT陶瓷和在较高烧结温度下制备的PSTZT陶瓷的热释电系数较大.The pyroelectric coefficients of the PSTZT ceramics which was sintered at different temperature and doped with PZT in different percentage were measured by using static method. It was founded that the pyroelectric coefficient of PSTZT ceramics was decreasing with the doping content of PZT increasing. The PSTZT ceramics prepared by two-step-sintering method or sintered at higher temperature possess higher pyroelectric coefficient.
