Bismuth titanate niobate-based relaxor ferroelectric ceramic material for energy storage and preparation method and application of bismuth titanate niobate-based relaxor ferroelectric ceramic material
The invention relates to a bismuth titanate niobate-based relaxor ferroelectric ceramic material for energy storage and a preparation method and application thereof, the general formula of the relaxor ferroelectric ceramic material is Bi (3-x) LaxTiNbO9, and x is more than or equal to 0 and less than or equal to 1.1; the relaxor ferroelectric ceramic material is prepared by doping lanthanum with Bi3TiNbO9 on the basis of a solid-phase sintering method. The lanthanum doping is performed by using an oxide of lanthanum. The preparation method has the advantages that the obtained bismuth titanate niobate-based relaxor ferroelectric energy storage ceramic material effectively overcomes the problems of low available energy storage density and energy storage efficiency of a traditional ferroelectric material, especially a bismuth layered ferroelectric material; the energy storage performance of the bismuth-doped titanium niobate ferroelectric ceramic material is obviously superior to that of undoped titanium niobate bismuth ferroelectric ceramic and other bismuth-layered ferroelectric ceramic materials, and meanwhile, the bismuth-doped titanium niobate ferroelectric ceramic material has relatively good working environment stability; the preparation method has the advantages of simple process, easily available raw materials and high production efficiency, and is suitable for large-scale actual production and application.
本发明涉及一种用于储能的钛铌酸铋基弛豫铁电陶瓷材料及其制备方法和应用，该弛豫铁电陶瓷材料的通式为Bi3‑xLaxTiNbO9，0≤x≤1.1；该弛豫铁电陶瓷材料是基于固相烧结法进行镧掺杂Bi3TiNbO9制备而成；所述镧掺杂是以镧的氧化物进行掺杂。本发明具有的优点是所得钛铌酸铋基弛豫铁电储能陶瓷材料有效克服了传统铁电材料尤其是铋层状铁电材料可利用储能密度和储能效率偏低的问题，使本发明的储能性能明显优于未掺杂的钛铌酸铋铁电陶瓷和其他铋层状铁电陶瓷材料，同时具备较好的工作环境稳定性；本发明制备方法工艺简单、原料易得、生产效率高，适合于大规模的实际生产应用。
