摘　　要：本文研究了采用机械球磨法工艺制备亚微米级Li3PO4粉末时固液比、球料比、球磨时间等参数对粉末粒度的影响：过高或过低的固液比都不利于粉末的细化;球料比和球磨时间对粉末粒度影响较大,增长球磨时间或加大球料比不一定会起到进一步细化的作用,反而会加大Al2O3杂质的引入。为得到亚微米级且纯度较高的Li3PO4粉末,减少Al2O3杂质的含量,经多次实验得到最佳工艺条件为：固液比1∶0.8,球料比l2∶l,球磨时间96h。Submicron Li3PO4 powder is prepared by mechanical milling.Study is made on the influences of ratio of solid to liquid, ratio of ball to powder and milling time on powder were studied.Higher or lower ratio of solid to liquid is not good for further refinement of Li3PO4.The influences of ratio of ball to powder and milling time was very important.Too long milling time and too big ratio of ball to powder may not result in finer powder,but increase the AlzO3 impurity content.In order to obtain higher purity SubmicronLi3PO4 powder, the best condition of Li3PO4 preparation would be as follows：ratio of ball to powder is 1：0.8,ratio of solid to liquid is 1：0.8,milling time is 96h
