Preparation process and properties of AlON samples

Caption

A novel ultra-fast high-temperature pre-sintering (UHS) followed by conventional pressureless sintering (CS) strategy was employed for the first time to prepare transparent AlON ceramics. The prepared AlON ceramics show high transmittance (≥80%) over a wide wavelength range of 350-4900 nm. The high relative density of the UHSed sample, along with the predominance of small grains and potential non-equilibrium grain boundaries induced by UHS, contributes to the rapid densification of AlON during subsequent CS.
