Regulation of the sintering trajectory of Ho,Pr:Y2O3 ceramics for 2.9 μm mid-infrared lasers by atmospheric sintering

Journal of Advanced Ceramics
The sintering trajectory of the Ho,Pr:Y2O3 ceramics could be effectively adjusted by sintering in a flowing oxygen atmosphere instead of vacuum. The final-stage grain growth was significantly suppressed by the use of oxygen atmosphere presintering ...
