碳热还原法制备氮化铝反应机制的研究进展

Review of Mechanisms of Carbothermal Reduction Nitridation Reactions

本文综述了碳热还原反应制备ＡｌＮ的各种反应机制，并进行了评述，详述了气－固反应机制和固－固反应机制的特点、实验证据及存在的不足。认为Ａｌ２Ｏ３蒸发分解零级反应与固相扩散反应共存的机理能较好地解释目前的实验现象，但仍需进行完善。

Several mechanisms of AlN synthesis by carbothermal reduction nitridation method were reviewed.The contents,evidences,experimental phenomena and drawbacks of two mechanisms, i.e.gas-solid reaction and solid-solid reaction mechanisms were discussed in details.It was believed that the evaporation reaction mechanism and solid-solid reaction mechanism coexisted in the carbothermal reduction nitridation process.Compared with others,this theory seemed more rational and could explain more experimental results.
