Aluminum nitride oxide transparent ceramics have attracted much attention due to their excellent optical properties,mechanical properties,dielectric properties,and chemical stability.AlON transparent ceramics have developed rapidly,but there are still some problems that seriously hinder their industrialization.Therefore,this article introduces two of the most commonly used methods for preparing AlON powder,including high-temperature solid-state reaction method and aluminum oxide reduction nitridation method.A systematic summary of sintering processes is conducted,including pressureless sintering,hot pressing sintering,hot isostatic pressing sintering,microwave sintering,and discharge plasma sintering.The advantages and disadvantages of AlON raw material powder and ceramic preparation methods are compared and analyzed.In addition,the influencing factors on the optical and mechanical properties of AlON transparent ceramics are explored.Finally,the problems and development trends faced by AlON transparent ceramics are discussed.
