Zirconium tin niobate calcium lead ceramic and preparation method and application thereof
The invention belongs to the technical field of dielectric materials, and discloses zirconium tin niobate calcium lead ceramic as well as a preparation method and application thereof. The molecular formula of the zirconium tin lead calcium niobate ceramic is (Pb < 0.93 > Ca < 0.07 >) (Zr < 0.975-x > Sn < x >) Nb < 0.02 > O < 3 >, wherein x is equal to 0.3 to 0.45. According to the preparation method, a traditional solid-phase reaction method, a tape casting process and a two-step sintering method are utilized, high-content Ca < 2 + > and Nb < 5 + > are introduced on the basis of PZ antiferroelectric ceramic, and the energy storage performance of the zirconium tin calcium lead niobate ceramic is explored by adjusting different zirconium tin ratios. When x is equal to 0.4, the (Pb0. 93Ca0. 07) (Zr0. 575Sn0. 4) Nb0. 02O3 ceramic has high effective energy storage density (Wre is equal to 14.60 J/cm < 3 >) and high energy storage efficiency (eta is equal to 85.58%), and can be applied to a dielectric energy storage capacitor.
本发明属于电介质材料技术领域，公开了一种锆锡铌酸钙铅陶瓷及其制备方法和应用。所述锆锡铌酸钙铅陶瓷的分子式为(Pb0.93Ca0.07)(Zr0.975‑xSnx)Nb0.02O3,x＝0.3～0.45。本发明利用传统固相反应法、流延工艺和两步烧结法，在PZ反铁电体陶瓷基础上引入高含量Ca2+和Nb5+，通过调节不同锆锡比来探究锆锡铌酸钙铅陶瓷的储能性能。当x＝0.4时，(Pb0.93Ca0.07)(Zr0.575Sn0.4)Nb0.02O3陶瓷具有高的有效储能密度(Wrec＝14.60J/cm3)和高储能效率(η＝85.58％)，可应用在电介质储能电容器中。
