“…The advantage of this method is using low cost, high purity, fine particle, and easily available aluminum and Al 2 O 3 powders as raw materials instead of expensive AlN powders. At present, much work has been conducted to synthesize AlON by aluminothermic reduction in N 2 atmosphere . However, this method of AlON synthesis still makes its high production cost due to the need of high purity nitrogen.…”

Aluminum oxynitride spinel (AlON) powders were synthesized by aluminothermic reaction in a reducing N 2 -CO atmosphere. Low cost and easily available aluminum and c-Al 2 O 3 alumina micrometer-sized powders were employed as starting materials. Mixed powders consisting of 75 wt% Al and 25 wt% Al 2 O 3 were milled together and pressed into billets with diameter of 20 mm and height of 15 mm. Green-body billets were then calcined in charcoal-protected condition (namely in a N 2 -CO atmosphere) at 1600°C. Phase composition and microstructure of final sintered products were analyzed. The results showed that AlON phase with AlN as a minor phase was formed at 1600°C for 3 h. At the same time, grains of AlON were tabular in shape and whiskers can be found in samples after being sintered at 1600°C.

Aluminium oxynitride (AlON) has a unique thermal and chemical stability that makes it the perfect candidate for a wide range of applications. This article provides a brief description and comparison of the most common AlON preparation methods along with their advantages and disadvantages. Although there has been extensive research on the material, especially more recently because of increased commercial interest, extensive systematic powder synthesis and processing studies have not been carried out to determine alternate, more cost efficient routes to fully dense transparent bodies. Further optimization of reaction sintering and transient liquid phase sintering could be important processing routes.

“…It will need long holding time, in general, more than 12 hours [10][11][12][13] . But in this work, singlephase γ-AlON transparent ceramic can be fabricated by one-step method at 1850 for 6h.…”

“…YUAN XianYang [10] fabricate transparent γ-AlON ceramic which has an in-line transmission of 60% (at 600nm), but it need to be sintered at 1950℃ for 12h. For this, many researchers in this area have worked to improve the preparation process of one-step method in different ways [11][12][13]. For example, Pei Xinmei et al [11] test the recently developed reaction-bonded aluminum notride (RBAN) technology, and dense AlON and Al 2 O 3 -AlON ceramics are obtained at 1750℃ with Al is nitrided to form nano-sized AlN particles during the nitridation process, but the prepared ceramics are nontransparent.…”
