YAG transparent ceramic and densification sintering method thereof
The invention provides a YAG transparent ceramic and a densification sintering method thereof, Y3Al5O12 is adopted in a traditional YAG transparent ceramic formula, the molar ratio of Y2O3 to Al2O3 is3: 5, and SiO2, MgO, CaO, LiF and other sintering aids are used as auxiliary materials to promote densification. According to the invention, no other sintering aid is added, and impurities or defectscaused by the addition of the sintering aid are avoided. The high-transparency YAG transparent ceramic material is prepared by introducing trace Y ion vacancy (the chemical formula is Y3-xAl5O12-1.5x), reducing the sintering temperature and combining a vacuum sintering technology and a hot isostatic pressing sintering technology.
一种YAG透明陶瓷及其致密化烧结方法，传统的YAG透明陶瓷配方采用Y3Al5O12，Y2O3与Al2O3的摩尔比为3:5，辅以SiO2、MgO、CaO、LiF等烧结助剂促进致密化。本发明不添加其它任何烧结助剂，避免因烧结助剂的添加引入杂质或缺陷。通过引入微量Y离子缺位（化学式为Y3‑xAl5O12‑1.5x），降低烧结温度，结合真空烧结与热等静压烧结技术，制备高透明YAG透明陶瓷材料。
