| Abstract: | Polycrystalline, transparent YAG (Y3AI5O12) ceramics were fabricated by a solid-state reaction method using high-purity Al2O3 and Y2O3 powders. The mixed powder compacts were sintered at 1600° to 1850°C for 5 h under vacuum. Optical transmittance in the region between the ultraviolet and infrared wavelengths for YAG ceramics (1 mm thick) sintered at 1800°C was similar to that for a YAG single crystal. |
