| Abstract: | Iron(III) phosphate dihydrate was synthesized using FeSO4, H3PO4, NaClO3, and NaOH as starting materials. For synthesis of FeSO4 · 2H2O the optimum molar ratios are FeSO4/H3PO4=1/5, FeSO4/NaClO3 = 6/1, FeSO4/NaOH= 1 / 2 and the optimum
temperature is 85℃. It was found that the dehydration process is FePO4 · 2H2O (-2H2O)→(166.2℃)
FePO4 and FePO4 · 2H2O is a very good anticorrosive and non-poisonous pigment. |
