以氧化铝纤维为原料，采用NH 5-C3 H8混合气体作为还原氮化剂，成功地合成了氮化铝纤维。扫描电镜观察表明，氮化纤维的形貌与原氧化铝纤维完全相同，保持了原氧化铝纤维的规则形状和光滑表面。通过一步合成工艺，在1400 ℃下在0.5 h内将高达95%的起始氧化铝转化为氮化铝。
Aluminum nitride fibers were successfully synthesized from alumina fibers using an NH5-C3H8 gas mixture as a reduction-nitridation agent. Observation using SEM clearly demonstrated that the morphology of the nitrided fibers was exactly the same as that of the raw alumina fibers, retaining the original regular shape and smooth surface. Up to 95% of the starting alumina was converted to aluminum nitride at 1400degreesC within 0.5 h via a single-step synthesis process.
