Magneto-optical transparent ceramic with excessive Ce doping as well as preparation method and application of magneto-optical transparent ceramic
The invention discloses a Ce-excessive-doped magneto-optical transparent ceramic and a preparation method and application thereof.The general chemical formula of the magneto-optical transparent ceramic is xwt% Ce: Tb3Sc2Al3O12. The preparation method comprises the steps that S1, powder containing Tb4O7, Sc2O3, Al2O3, CeO2 and a sintering aid is subjected to compression molding, and a biscuit is obtained after cold isostatic pressing; and S2, pre-sintering the biscuit obtained in the step S1, carrying out vacuum sintering, and annealing to obtain the magneto-optical transparent ceramic. The series of magneto-optical transparent ceramics have the characteristics of high Verdet constant, high density, excellent optical quality and uniform internal crystal grains, are loaded in a magneto-optical isolator as a core material, and are of great significance to miniaturization of the magneto-optical isolator.
本申请公开了一种Ce过量掺杂的磁光透明陶瓷及其制备方法和应用，所述磁光透明陶瓷的化学通式为xwt％Ce:Tb3Sc2Al3O12，所述制备方法包括:S1，将含有Tb4O7、Sc2O3、Al2O3、CeO2、烧结助剂的粉体压制成型、冷等静压后获得素坯；S2，将步骤S1获得的素坯预烧结、真空烧结、退火，获得所述磁光透明陶瓷。该系列磁光透明陶瓷具有高费尔德常数、高致密度特性，光学质量优异、内部晶粒均匀，作为核心材料装载在磁光隔离器中，对磁光隔离器小型化具有重要意义。
