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Al2O3-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。

Abstract: Transparent γ-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-phase γ-AlON powders with less agglomeration, uniform distribution of particle size are critical in sintering highly transparent γ-AlON ceramics. In this paper, Al2O3-AlN phase diagrams and thermodynamic calculation results of γ-AlON are briefly introduced. And then, the research progress of γ-AlON powders synthesized by high temperature solid-state reaction, aluminothermic reduction nitridation, and carbothermal reduction nitridation, respectively, is reviewed. Finally, the future synthesis technologies for γ-AlON powder with <100 nm size are proposed.

Key words: aluminum oxynitride, powder synthesis, high temperature solid-state reaction, aluminothermic reduction nitridation, carbothermal reduction nitridation
