采用常规固相反应法制备了掺杂锰的氧化钨（K0.16Na0.84）0.5Bi4.5Ti4O15（KNBT）。研究了锰掺杂对KNBT陶瓷结构和电性能的影响。采用x射线衍射分析（XRD）和拉曼光谱进行物相分析。用扫描电子显微镜（SEM）观察其显微组织形态。与KNBT陶瓷相比，锰改性KNBT陶瓷的压电性能得到了显著提高。KNBT-Mn50陶瓷的压电系数（d33）最大值为28 pC/N，同时具有高居里温度（Tc ~ 657℃）和高电阻率（高于106Ω cm）。此外，锰改性KNBT无铅压电陶瓷具有良好的压电性能温度稳定性。
Aurivillius oxides, (K0.16Na0.84)0.5Bi4.5Ti4O15(KNBT) with manganese doping, were synthesized by using the conventional solid state reaction method. Influence of manganese doping on structure and electric properties of the KNBT ceramics was investigated. Phase analysis was performed by X-ray diffraction analyses (XRD) and Raman spectroscopy. Microstructural morphology was assessed by the scanning electron microscopy (SEM). Piezoelectric performances of manganese modified KNBT ceramics were improved significantly compared with that of the KNBT ceramic. The maximum of piezoelectric coefficient (d33) was found to be 28 pC/N for the KNBT-Mn50 ceramic, together with high Curie temperature (Tc∼ 657 °C) and high resistivity (higher than 106Ω cm). In addition, excellent temperature stability of piezoelectric performances was exhibited for manganese modified KNBT lead-free piezoelectric ceramics.
