Preparation method of yttrium oxide transparent ceramic with high visible light transmittance
The invention discloses a preparation method of yttrium oxide transparent ceramic with high visible light transmittance. The preparation method comprises the following steps: carrying out ball milling, dry pressing molding and cold isostatic pressing molding on a high-purity Y2O3 raw material to obtain a biscuit, and sequentially carrying out vacuum sintering, hot isostatic pressing sintering andhydrogen atmosphere heat treatment. Compared with the traditional air or oxygen heat treatment process, higher visible light transmittance can be achieved through the hydrogen atmosphere heat treatment. The visible light transmittance of the ceramic reaches up to 80%.
本申请公开了一种高可见光透过率氧化钇透明陶瓷的制备方法，采用高纯Y2O3原料，经球磨、干压成型以及冷等静压成型得到素坯，然后依次经过真空烧结、热等静压烧结和氢气气氛热处理。本发明通过氢气气氛热处理，相比于传统空气或氧气热处理工艺，具有更高的可见光透过率。陶瓷在可见光透过率高达80%。
