I put fe2o3, h3po4, and water in the reactor to make FePO4-2H2O (dehydrate) and react at 70~100℃ for 24 hours. (metal/P = 0.97~0.99) Then I measured the pH of the solution that was made, and it came out as 1.6-1.7 (supernatant). What are the factors that affect the LFP finally made depending on the precursor pH of the manufactured FePO4-2H2O?
