“…Until now, most of the transparent AlON components are prepared by conventional pressureless sintering, hot pressing, or hot isostatic pressing techniques . However, conventional fabrication of AlON ceramics usually requires sintering of a green body at high temperature (≥1850°C) for a long holding period (≥6 hours) . Even by using an AlON powder with bimodal particle size distribution (PSD), combined with keeping its bimodal PSD throughout the whole sintering time to shorten the densification process, the holding period of 1.5‐2.5 hours is still required at high temperatures of 1820‐1880°C (40°C/min) .…”

“…Over the next several years, other researchers confirmed that a spinel-type phase named aluminum oxynitride (AlON) indeed exists in this system [11][12][13][14]. As a new ceramic material, AlON offers researchers additional options in oxide-non-oxide systems [15][16][17].…”

“…Synthesis methods include solid‐state reaction method, aluminothermic reduction nitridation method, and carbothermal nitridation method (CRN) . The synthetic AlON powder can be sintered into ceramics by hot‐pressing method, hot isostatic pressing method, and pressurless sintering method . Particularly, combing carbothermal nitridation method with pressurless sintering method is preferred due to its low cost, which enables potential commercialization with large‐scale production for highly transparent AlON ceramics.…”

“…After planetary ball‐milling for 24 hours at 170 R/min, bimodal PSD fine powders at 1.1 and 2.2 μm were obtained and used for fabricating highly transparent ceramics with the fast pressureless sintering method. Liu et al prolonged the planetary ball‐milling time of AlON powders to 24 hours at 130 R/min, resulting in powders with an average particle size of 1.38 μm that can be further sintered into highly transparent AlON ceramics. Despite of being an effective method, the details of planetary ball‐milling method are not usually given in previous studies, and planetary ball‐milling received little systematic studies on the mechanism and controlling parameters while employed in processing AlON powders.…”
