  • INQUIRY

Ammonium dihydrogen phosphate, also known as monoammonium phosphate, has white grains. It is mainly used as fertilizer and fireproof agent for wood, paper and fabric, as well as pharmaceutical and ruminant feed additives. It can also be used in the preparation of lithium iron phosphate and other battery cathode materials,


The technical index of battery grade ammonium dihydrogen phosphate, especially the impurity content, is higher than that of food grade. Because the battery grade ammonium dihydrogen phosphate needs strict dehydration treatment and nano grinding treatment in the early stage of electrode fabrication, the quality of battery grade ammonium dihydrogen phosphate grain will affect the pretreatment process cost and electrode product quality of subsequent electrode fabrication.
