Abstrakt: Iron(III) phosphates have been synthesized directly under mild hydrothermal conditions. The reaction of FeCl3, H3PO4 and (NH2)2CO aqueous solutions at 180 °C leads to the formation of four individual compounds: FePO4·2H2O, Fe(NH4)(HPO4)2, Fe2(NH4)(OH)(PO4)2·2H2O and Fe(NH3)2PO4. The reaction product depends on the Fe∶P∶C molar ratio in the reaction mixture. The effect of urea on the reaction route is discussed.
