【摘要】 采用机械合金化法,以Si粉和Mo粉为原料制备MoSi2,分析球磨机转速、球料比以及球磨时间等因素对产物的影响,并采用扫描电镜、X射线衍射等测试手段对产物的结构和相组成进行分析,结果表明,在球磨助剂的作用下,当球料比为20:1时,在600r/min的转速下球磨48h,能够获得颗粒细小的合金化MoSi2金属间化合物粉体。
【Abstract】 With Si powders and Mo powders as reactant,MoSi2 compound was synthesized by mechanical alloying. The effect of ball milling charge ratio,ball to powder weight ratio and time on the mechanical alloying synthesis of MoSi2 were studied.XRD and SEM were used to analyze the structure and phase composition.The results show that fine grain of MoSi2 intermetallic compound powder were obtained with milling additives,20: 1 of ball to powder weight ratio,600r/min of ball milling charge ratio,48h of ball milling time.
【Key words】 mechanical alloying； MoSi2； ball to powder weight ratio； synthesis；
