Abstract
- In this study, highly transparent aluminate oxynitride (AlON) ceramics were prepared via the reactive sintering of Al2O3 and AlN powders using a Y2O3‐MgAl2O4‐H3BO3 ternary sintering additive. The ternary doping process resulted in the efficient preparation of transparent AlON ceramics with small grains and high transmittance as compared to the binary doping (Y2O3‐MgAl2O4) process. The addition of 0.1 wt.% Y2O3‐0.4 wt.% MgAl2O4‐0.12 wt.% H3BO3 resulted in the formation of a 4‐mm‐thick AlON ceramic with high transmittance (81% at 600 nm) and low haze (3.46%). This is the best performance in terms of the thickness and transmittance reported for AlON transparent ceramics prepared by the reactive sintering method. [ABSTRACT FROM AUTHOR]
