Sodium bismuth titanate-based lead-free textured ceramic with high electroinductivity and ultra-low hysteresis and preparation of sodium bismuth titanate-based lead-free textured ceramic
The invention relates to the technical field of functional ceramics, and relates to a sodium bismuth titanate-based lead-free textured ceramic with high electroinductivity and ultralow hysteresis and preparation thereof, the chemical composition of the ceramic is 0.76 Bi < 0.5 > Na < 0.5 > TiO < 3 >-0.24 SrTiO < 3 >-MnO-CuO-SrTiO < 3 >-NaNbO < 3 >. Compared with the prior art, the sodium bismuth titanate-based lead-free piezoelectric textured ceramic prepared by the invention has the advantages that strontium titanate and a sodium niobate template are mixed, so that the preparation method is simple, the preparation cost is low, and the preparation method is suitable for large-scale preparation of the sodium bismuth titanate-based lead-free piezoelectric textured ceramic with high electroinductivity and ultralow hysteresis. According to the preparation method, the sodium bismuth titanate-based lead-free piezoelectric textured ceramic with a relatively high texture degree is obtained by combining the advantages of the sodium bismuth titanate and the sodium niobate template, and meanwhile, the sodium niobate template also plays a doping role, so that the relaxation degree of a system is effectively improved, and the hysteresis is greatly reduced.
本发明涉及功能陶瓷技术领域，涉及一种具备高电致应性及超低滞后的钛酸铋钠基无铅织构陶瓷及其制备，该陶瓷的化学组成为0.76Bi0.5Na0.5TiO3‑0.24SrTiO3‑MnO‑CuO‑SrTiO3‑NaNbO3，与现有技术相比，本发明制备出的钛酸铋钠基无铅压电织构陶瓷将钛酸锶和铌酸钠模板混合，结合两者的优势，获得了较高织构度的钛酸铋钠基无铅压电织构陶瓷，同时铌酸钠模板又起到了掺杂的作用，有效的提升了体系的弛豫程度，大大降低了滞后。
