摘要
以钛铁矿和石墨为原料,在N2气氛下通过碳热还原法制备了粒度均匀的微米Ti(C,N)粉。结合X射线衍射分析,主要研究了Ti(C,N)粉制备过程中配碳量、反应温度、保温时间、N2分压对C/N的影响规律,获得了C/N控制关键因素及量化控制参数。
Ti（C,N） micron powder was synthesized using ilmenite and graphite as raw materials via carbothermic reduction under nitrogen atmosphere.The influence of carbon contents,reaction temperature,holding time and nitrogen partial pressure on C/N control of TiC1-xNx powder was mainly investigated by X-ray diffraction.The C/N control critical factors and quantitative relationship were obtained.
