KNN-based transparent multifunctional ceramic material with photochromic behavior and preparation method thereof
The invention discloses a KNN-based transparent multifunctional ceramic material with photochromic behavior and a preparation method thereof, the specific component is (K0. 5Na0. 5) 0.99-xEu0. 01LaxO3, x ranges from 0.005 to 0.03, dry-pressing tabletting forming and cold isostatic pressing are combined, double-layer buried sintering is carried out at 1140-1150 DEG C to form ceramic, and the KNN-based transparent multifunctional ceramic material with a single perovskite phase, small crystal grains, small particle sizes, large particle sizes and the like can be prepared. The invention discloses a KNN-based transparent multifunctional ceramic material with a compact structure. The material has the advantages of high transparency, high energy storage density, excellent photochromism, good fluorescence regulation and control characteristic and uniform and consistent grain size. The method can be used for preparing the lead-free KNN-based ferroelectric ceramic material with high transparency, high energy storage density, excellent photochromism and good fluorescence regulation and control characteristic by combining ion doping modification and process optimization.
本发明公开了一种具备光致变色行为的KNN基透明多功能陶瓷材料及其制备方法，具体组分为(K0.5Na0.5)0.99‑xEu0.01LaxO3，其中x范围为0.005‑0.03，结合干压压片成型和冷等静压，并在1140～1150℃下双层埋烧烧结成瓷，即可制得单一钙钛矿相，具有小晶粒，结构致密的KNN基透明多功能陶瓷材料。这种材料具有透明度高、储能密度高，光致变色优异、荧光调控特性好、晶粒尺寸均匀一致，这种方法结合离子掺杂改性和工艺优化的方式能制备具有透明度高、储能密度高，光致变色优异、荧光调控特性好的无铅KNN基铁电陶瓷材料。
