摘　　要：介绍了几种La(OH)3的制备方法。针对我国目前La(OH)3粉体制备工艺复杂、能耗大、产品纯度低及成本高等特点,提出一个新的高效制备La(OH)3的工艺思路,该思路既符合国家节能减排政策,又满足新材料产业快速发展对稀土粉体材料的需求。The preparation methods for La（OH）3 were introduced. The process of preparing La（OH）a powder are complex, high energy consumption, low purity, high cost. This article offers a idea for preparing La （OH）3 powder which conforms to the national energy conservation and emissions reduction,and meets the needs of the new material industry rapid development for rare earth powder materials.
