%X FRL-FRH phase transitional composite ceramics were prepared. The pyroelectric effect of theceramics was investigated. The output of pyroelectric current during the FRL-FRH phase transitionwas simulated by a computer. The results indicated that ion diffussion exists on the interfacebetween neighbour compositions. The influence of ion diffussion to the macroscopic pyroelectriceffect depends on the phase transitional property of relative compositions. The computer speculationmethod for pyroelectric current of multicomposition ceramics is an effective way to analyse thesituation of ion diffussion, and it is also helpful to design and study new functional materials.
