Preparation and characterization of nanoscale flaky iron phosphate from phosphating slag
Abstract
Nanoscale flaky FePO4·2H2O was prepared in PTFE lined reactors by hydrothermal recrystallization method. Explored effects of different hydrochloric acid concentrations on purity, particle size, crystal structure and micromorphology. The addition of hydrochloric acid improved the purity of the iron phosphate in the phosphating slag. During the acidity increasing, average particle size decreased, crystal orientation changed twice. At the concentration of hydrochloric acid was 8wt.%, iron phosphate crystal has the best crystallinity, morphology changed into flake with 58.8 nm thickness.
