Scintillation ceramic as well as preparation method and application thereof
The invention discloses scintillation ceramic and a preparation method and application thereof, the preparation method comprises the following steps: (1) carrying out ball milling I on raw materials containing Y2O3, La2O3, Eu2O3, lanthanide rare earth oxide, a sintering aid and a ball milling aid, and drying I to obtain [Y < 0.85-x-y > La < 0.15 > EuxMy] 2O3 powder; and (2) carrying out presintering I, ball milling II and drying II on the obtained [Y < 0.85-x-y > La < 0.15 > Eu < x > M < y >] < 2 > O < 3 > powder to obtain the ceramic powder, (3) performing compression molding on the obtained ceramic powder to obtain a biscuit; and (4) pre-sintering the obtained biscuit II, performing vacuum sintering, and annealing to obtain the scintillation ceramic. The series of red-light ceramics have the characteristics of steady-state luminescence, uniform light output, excellent irradiation stability and low detection limit. And the scintillation transparent ceramic is stable in structure, so that long-term stable work under x-ray irradiation can be realized.
本申请公开了一种闪烁陶瓷及其制备方法和应用，所述制备方法包括：(1)将含有Y2O3、La2O3、Eu2O3、镧系稀土氧化物、烧结助剂、球磨助剂的原料球磨I、干燥I，获得所述[Y0.85‑x‑yLa0.15EuxMy]2O3粉体；(2)将获得的[Y0.85‑x‑yLa0.15EuxMy]2O3粉体预烧结I、球磨II、干燥II，获得所述陶瓷粉体；(3)将获得的陶瓷粉体压制成型后获得素坯；(4)将获得的素坯预烧结II、真空烧结、退火，获得所述闪烁陶瓷。该系列红光陶瓷具有稳态发光特性、均匀的光输出、优异的辐照稳定性和低的检测极限。并且由于闪烁透明陶瓷的结构稳定，可以实现在x射线照射下的长期稳定工作。
