摘　　要：对以ＮｂＯ２为原料的碳热还原氮化的工艺条件进行了热力学分析。以Ｎｂ２Ｏ５粉和ＮｂＯ２粉为原料，制得了较纯的ＮｂＮＯ粉和ＮｂＮ０．９Ｏ０．１粉。对两种粉粒分别用Ｘ－ｒａｙ衍射法和扫描电镜进行了较详细的晶相结构测定和形貌观察，对结果进行了初步讨论。Thermodynamic analysis for the synthesis of NbN from NbO 2 with carbothermal reduction is performed. The relatively pure powders of NbNO and NbN 0.9 O 0.1 are prepared with Nb 2O 5 and NbO 2 The structural analysis and topographical observation are performed by X-ray diffraction and scan electron microscope respectively The experimental results are discussed preliminarily.
