Highly transparent YO ceramics were successfully fabricated with CaO as sintering aid. The microstructure evolution, optical transmittance, hardness and thermal conductivity of the YO ceramics were investigated. It was found that doping a small amount (0.01-0.15 wt.%) of CaO could greatly improve the densification rate of YO. With an optimized CaO dosage of 0.02 wt.% combined with the low temperature vacuum sintering plus hot isostatic pressing (HIP-ing), YO ceramics with in-line transmittance of 84.87% at 1200 nm and 81.4% at 600 nm were obtained.
以CaO作为烧结助剂成功制备了高透明度的YO陶瓷。研究了YO陶瓷的微观结构演变、光学透过率、硬度和热导率。结果发现，掺杂少量（0.01-0.15 wt.%）的CaO可显著提高YO的致密化速率。通过优化CaO用量为0.02 wt.%，并结合低温真空烧结和热等静压（HIP）工艺，获得了在1200 nm处的直线透过率为84.87%、在600 nm处为81.4%的YO陶瓷。
