摘　　要：γ-AlON透明陶瓷具有硬度大、化学稳定性好以及光学透过率高等优点,在国防与商业领域具有广阔的应用前景。高纯超细、粒径分布均匀、几乎无团聚的单相γ-AlON粉体是制备高透明γ-AlON陶瓷的关键。本文首先对Al_(2)O_(3)-AlN相图及γ-AlON的热力学计算结果进行了简要介绍,然后综述了高温固相反应、铝热还原氮化、碳热还原氮化三种方法合成γ-AlON粉体的研究进展,最后对粒径小于100 nm的γ-AlON粉体合成方向进行了展望。Transparentγ-AlON ceramics have the advantages of high hardness,good chemical resistance and high optical transmittance,and have extensive application prospects in national defense and commercial fields.Whereas,high-purity single-phaseγ-AlON powders with less agglomeration,uniform distribution of particle size are critical in sintering highly transparentγ-AlON ceramics.In this paper,Al_(2) O_(3)-AlN phase diagrams and thermodynamic calculation results ofγ-AlON are briefly introduced.And then,the research progress ofγ-AlON powders synthesized by high temperature solid-state reaction,aluminothermic reduction nitridation,and carbothermal reduction nitridation,respectively,is reviewed.Finally,the future synthesis technologies forγ-AlON powder with<100 nm size are proposed.
