AbstractThe densification of transparent AlON ceramics was investigated with the aid of Y2O3, LA2O3and MgO as sintering agents. It was found that the density of the AlON ceramics obtained after co-doping with Y2O3and LA2O3could be further improved with the addition of a small amount of MgO. The relative density of the AlON ceramic reached 99.9 % when it was co-doped with 0.08 wt% Y2O3+ 0.02 wt% LA2O3+0.2 wt% MgO after undergoing pressureless sintering at 1900 °C for 24 h. It is argued that Y3+and Mg2+can decelerate grain boundary mobility, suppress grain growth and promote the elimination of pores. © 2017 Göller Verlag.
