Magneto-optical transparent ceramic as well as preparation method and application thereof
The invention discloses magneto-optical transparent ceramic and a preparation method and application thereof.The general chemical formula of the magneto-optical transparent ceramic is Ho3Sc2Al3O12, the preparation method comprises the steps that S1, mixed powder containing holmium oxide, scandium oxide, aluminum oxide and a sintering aid is subjected to compression molding, and then a biscuit is obtained; 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 prepared magneto-optical transparent ceramic has excellent linear transmittance, stable thermal performance and high magneto-optical performance, and compared with a mainstream commercial terbium-based magneto-optical material, the preparation method adopted by the magneto-optical transparent ceramic has the advantages of being low in raw material cost and low in preparation cost. And the application of the magneto-optical transparent material in an optical isolator or an optical modulator can be further promoted.
本申请公开了一种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Ho3Sc2Al3O12，所述制备方法包括：步骤S1，将含有氧化钬、氧化钪、氧化铝、烧结助剂的混合粉体压制成型后获得素坯；步骤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。所制备的磁光透明陶瓷具有优秀的线性透过率，稳定的热学性能，较高的磁光性能，与主流的商用铽基磁光材料相比本申请中磁光透明陶瓷所采用的制备方法还具有原料成本低、制备成本低的优势。可以进一步推动磁光透明材料在光隔离器或光调制器中的应用。
