称取一定量的工业钼粉，分别加入1%La₂O₃和1%Mo₂C，放入行星式球磨机中，在氩气保护下球磨24 h，每球磨1 h停机8~10 min，同时改变球磨机转动方向，球料比为10：1；球磨转速为350r/min，所得钼粉标记为Mo-1%La₂O₃-350r和Mo-1%Mo₂C -350r。对球磨后钼粉使用XRD对粉末进行物相分析，步长8°/min，范围10~90°。将球磨后粉末加入含酒精的试管中超声震荡15min分散后，通过扫描电镜采集粉末形貌图像，并利用所采集的粉末SEM图像统计粉末粒径。

A certain amount of industrial molybdenum powder was weighed and added to 1% La₂O₃ and 1% Mo₂C, respectively, and put into a planetary ball mill and ball milled for 24 h under argon protection, with a stoppage of 8-10 min for each 1 h of ball milling, while changing the direction of ball mill rotation, with a ball-to-material ratio of 10:1; the ball milling speed was 350 r/min, and the resulting molybdenum powder was labeled as Mo-1% La₂O₃-350r and Mo-1% Mo₂C-350r. The molybdenum powders were analyzed by XRD in steps of 8°/min and in the range of 10-90°. The powder was added to a test tube containing alcohol and dispersed by ultrasonic shaking for 15 min, and the powder morphology images were collected by scanning electron microscopy, and the powder particle size was counted using the collected powder SEM images.
