Abstract Ho-modified NBT-BT ferroelectric ceramics were synthesized by a conventional solid state reaction. The changes in crystal structure and identification of functional groups in the prepared ceramics were studied by XRD and Raman studies. T-dependent dielectric study reveals a diffuse dielectric phase transitions were observed in the intervals of 200– A thermal stable dielectric constant was noted in long temperature intervals, with increases Ho-concentration. The polarization study indicates the deviation of loop shape from nearly square loop into slanted slim loop with Ho dopant. These observations indicate, NBHT-BT ceramics opens for energy harvesting and thermally stable dielectric materials applications.

观察 Ho - 改性 NBT - BT 无铅陶瓷中的扩散弛豫活性和正常热稳定性

摘要 通过常规固相反应合成了Ho修饰的NBT-BT铁电陶瓷。通过XRD和拉曼研究研究了制备的陶瓷中晶体结构的变化和官能团的鉴定。与 T 相关的介电研究表明，在 200 的间隔内观察到了扩散介电相变 - 在较长的温度间隔内观察到热稳定的介电常数，随着 Ho 浓度的增加。极化研究表明环路形状从近方形环路到带有 Ho 掺杂剂的倾斜细环路的偏差。这些观察结果表明，NBHT-BT 陶瓷可用于能量收集和热稳定介电材料应用。
