以5∶1、10∶1、20∶1、30∶1四种不同球科比采用机械合金化方法合成了MoSi_2粉末，通过X射线衍射仪和SEM研究并讨论了球料比对MoSi_2机械合金化过程的影响，指出装球量略小于球罐容积的2/3为宜。
MoSi 2 powders were synthesized by mechanical alloying method at four different ball ratios of 5: 1, 10:1, 20:1, 30:1. X-ray diffractometry and SEM were used to study and discuss the mechanical properties of MoSi 2 The impact of the process, pointed out that the amount of ball is slightly less than 2/3 of the volume of the spherical tank is appropriate.
