A novel three-step pressureless sintering (TSPS) method with coarse AlON powder (D50 = 2.54 ± 0.06 μm) was firstly reported for the preparation of highly transparent AlON ceramics. The high temperature of 2050 °C exists for only 5 min can significantly improves the mass transport rate and promotes grain growth, resulted in the elimination residual pores and densification. The as-prepared AlON ceramic possesses a maximum transmittance of 83.9% in the wavelength range of 2500–6000 nm, compared to 72.4% by a traditional one-step pressureless sintering. Thus, TSPS shows great potential for the low-cost preparation of AlON ceramics with high sintering efficiency and transmittance, utilizing coarse AlON powder.
