摘要： 高纯度的氮气中,以Al-Mg-Y合金为母合金,利用Lanxide技术合成了含烧结助剂Y2O3的复合AIN粉体.通过扫描电镜、X射线衍射、粒径分析及化学成分分析等检测手段对氮化产物进行表征.实验结果表明,合金氮化反应完全,氮化产物疏松易于粉化.粉化后获得的复合AIN粉体具有纯度高,氧杂质含量低,粒度细小等优点.

Abstract: Composite AlN powder, mixed with the sintering additive Y_2O_3, was synthesized by the direct
nitridation of molten Al-Mg-Y alloys. The character of products was determined by means of electron microscopy, X-ray diffraction,
granularmetric analysis and chemical composition analysis etc. The results show that the nitridation rate of the raw alloys is higher,
and the nitridation products are porous enough to be easily crushed. Composite AlN powder, obtained by the Lanxide method, has excellent
characters such as high purity, especially low oxygen content, and narrow well-distributed grain size and so on.

Key words: AIN powder, Lanxide method, aluminium alloys, sintering additives
