RARE-EARTH OXIDE BASED MONOLITHIC CHAMBER MATERIAL |
摘要 |
A solid sintered ceramic article may include a solid solution comprising Y2O3 at a concentration of approximately 30 molar % to approximately 60 molar %, Er2O3 at a concentration of approximately 20 molar % to approximately 60 molar %, and at least one of ZrO2, Gd2O3 or SiO2 at a concentration of approximately 0 molar % to approximately 30 molar %. Alternatively, the solid sintered ceramic article a solid solution comprising 40-100 mol % of Y2O3, 0-50 mol % of ZrO2, and 0-40 mol % of Al2O3. |
