摘要
利用特殊设计的球磨装置，经抽真空后充入一定压力的氮气，通过球磨纯金属，在室温下制备出金属氮化物的超细微粒。对不同球磨条件下制备的ＮｂＮ超细粉，采用ＸＲＤ、ＴＥＭ、ＤＳＣ对晶粒尺度、相结构及热稳定性进行了分析，研究不同球磨条件对ＮｂＮ超细粉结构的影响。
Ultra fine powders of NbN are
synthesized by simple milling of pure niobium in molecular nitrogen atmosphere at
roomtemperature. The Phase structure,grain size,and thermal stability of samples prepared
under different milling conditions have been investigated by XRD,TEM,and DSC in order to
study the influence of the milling conditions on the structure of metal nitride ultra fine powders.
