Preparation of potassium-sodium niobate-based ceramic and application of potassium-sodium niobate-based ceramic in buzzer
The invention discloses preparation of potassium-sodium niobate-based ceramic and application of the potassium-sodium niobate-based ceramic in a buzzer. The chemical formula of the potassium-sodium niobate-based ceramic is 0.97 (K < 0.48 > Na < 0.52 >) (Nb < 0.97 > Sb < 0.03 >) O < 3 >-0.03 Bi < 0.5 > Na < 0.5 > ZrO < 3 >. The potassium-sodium niobate-based ferroelectric ceramic has the beneficial effects that the potassium-sodium niobate-based ferroelectric ceramic is prepared by adopting a traditional solid-phase sintering method, Sb < 3 + > and Bi < 0.5 > Na < 0.5 > ZrO < 3 > are jointly added, so that a ceramic crystal structure is distorted, the potassium-sodium niobate-based ferroelectric ceramic with excellent electrical properties under a room-temperature condition is successfully prepared, the ceramic material can generate maximum polarization Pmax of 31.19 mu C/cm < 2 > and residual polarization Pr of 14.81 mu C/cm < 2 > under an electric field of 60kV/cm, and the potassium-sodium niobate-based ferroelectric ceramic has excellent electrical properties. And the film has better monopole strain capacity and dielectric property, and meets the performance requirements of mosquito dispeller and buzzer.
本发明公开了一种铌酸钾钠基陶瓷制备及其在蜂鸣器中的应用，该铌酸钾钠基铁电陶瓷的化学式为0.97(K0.48Na0.52)(Nb0.97Sb0.03)O3‑0.03Bi0.5Na0.5ZrO3。有益效果在于：本发明采用传统固相烧结法制备，共同添加Sb3+和Bi0.5Na0.5ZrO3使陶瓷晶体结构畸变，成功制备出了在室温条件下具有优异电性能的铌酸钾钠基铁电陶瓷，该陶瓷材料在60kV/cm电场下能够产生最大极化Pmax＝31.19μC/cm2，剩余极化Pr＝14.81μC/cm2，有较好的单极应变能力与介电性能，满足于驱蚊器与蜂鸣器的性能要求。
