单分散微米磷酸锂的制备

Preparation of monodisperse micron lithium phosphate

以提锂后的尾液为原料，与Na2CO3和Na3PO4·12H2O反应，在较为温和的水热条件下（120～150℃）、较短的反应时间内（3～10h）制得了单分散的球形Li3PO4颗粒。粒径约5～8μm，产率达到90％以上。该方法是一种环境友好的绿色化学制备方法，全过程接近污染物零排放，不仅解决了尾液的环境污染问题，而且还提高了盐湖资源的综合利用率。

Using raw brine after being extracted of lithium and sodium phosphate, a high quality monodisperse micron lithium phosphate was synthesized by hydrothermal synthesis under the conditions of 3--10 hours, 120--150 ℃, and with a very high yield. The target product Li3PO4 has fine crystal formation, the diameter of which is from 5 to 8 μm. The process features environment - friendly technology and methods of green chemistry, with its pollutants emission close to zero.
