摘　　要：以硫酸锰和磷酸为原料制备超细磷酸锰,采用正交法优化的最佳工艺条件为:反应温度80℃,表面活性剂的用量为原料锰盐质量的1.0%,磷锰投料比为1.5∶1.0(物质的量比),pH值为8.0。在此条件下得到的样品为片状磷酸锰,粒径分布均匀,平均粒径为815nm,所制备的LiMnPO4/C复合材料有较好的电学性能。Taking manganese sulfate and phosphoric acid as materials for the preparation of ultrafine manganese phosphate.Using the orthogonal method to optimize the process,the optimum conditions are confirmed as follows：the reaction temperature was 80 ℃,the surfactant was 1.0％ of the quality of manganese salt,the material mix ratio was 1.5 ∶ 1.0,the value of pH was 8.0.Under these conditions,the samples were flake manganese phosphate,its average particle diameter was 815 nm.The prepared LiMnPO4/C composites have good electrical properties.
