Chemical formula: FePO4.2H2O
Relative molecular weight: 186.85
Appearance: white or yellowish white powder
CAS number: 10045-86-0
Main application: It is mainly used as a raw material for lithium iron phosphate, which is the cathode material of ion batteries.
Ferric phosphate, also known as ferric phosphate and ferric orthophosphate, with molecular formula FePO4, is a white, off-white monoclinic crystal powder. It is a salt formed by the action of iron salt solution and sodium phosphate, in which iron is positively trivalent. Its main purpose is to manufacture lithium iron phosphate cathode materials, catalysts and ceramics.
