| Abstract: | Non-crystaline iron(III) triphosphate was prepared by the reaction of iron(III) oxide or iron(III) hydroxide with phosphoric acid under the conditions of P2O5 / Fe2O3 = 5 and T = 250-280℃ . When.it is heated at a temperature higer than 280℃ , crystaline iron(III) triphosphate, FeH2P3O10· 2H2O, was obtained. FeH2P3P10·2H2O was dehydrolyzed byheating as follows: FeH2P3O10·2H2O -2H2O→112.8#FeH2P3O10,-H2O→501# FePO3. Testsshowed that FeH2P3P10·2H2O is a good non-toxic anticorrosive pigment. |
