| Abstract: | The ferroelectric powder 0.96(Bi0.5Na0.5)TiO3-0.04Ba(Zr,Ti)O3(BNT-BZT) was synthesized by the solid-phase reaction method using BaCO3, Na2CO3, TiO2, ZrO2 and Bi2O3 as raw materials, and the BNT-BZT ceramic plate was prepared by the atmospheric sintering method. The effects of pressure and sintering temperature on the compactness of ceramics were investigated, and the structure, morphology and composition of BNT-BZT powder and ceramic plate were characterized.A pyroelectric nanogenerator based on BNT-BZT ceramicwas designedand its performance was studied. The results showed that the ceramic plate has the best compactness prepared under the conditions of a pressure of 7 MPa and a sintering temperature of 1 210 ℃. Under periodic cooling and heating conditions, the output peak current/voltage of the device reaches －18.5 nA/－0.9 V and 16.7 nA/0.8 V, respectively, which has excellent pyroelectric performance. |
