磷酸二氢铵应用研究进展

中国磷矿资源丰富，为磷酸盐工业的发展带来了重大机遇。磷酸二氢铵作为重要的磷酸盐系列产品之一，常用作氮-磷复合肥广泛使用，但肥料利用率低，附加值不高，造成资源浪费，阻碍了磷化工的发展。重点综述了磷酸二氢铵在灭火剂、阻燃剂、玻璃材料、磷酸铁锂材料和基体改进剂等领域的应用，为拓展磷酸二氢铵的应用领域、提高磷酸二氢铵附加值提供了借鉴。最后，对磷酸二氢铵今后的研究方向进行了展望。

Research progress in application of ammonium dihydrogen phosphate

China is rich in phosphate rock resources，which have brought great opportunities for the development of phosphate industry.Ammonium dihydrogen phosphate as one of important phosphate series products，commonly used for N-P compound fertilizer，but the fertilizer utilization rate is low，and value-added is not high，caused resource waste and hindered the development of phosphorus chemical industry.Applications of ammonium dihydrogen phosphate as fire extinguishing agent，flame retardants，glass material，lithium iron phosphate material and matrix modifier etc.were emphatically summarized， which provided reference for expanding the application fields and enhancing the added value of it. Finally，the research direction of the ammonium dihydrogen phosphate in the future was also prospected.
