The aim of this study was to look for a simple and easy method to prepare Fe 5 (PO 4 ) 4 (OH) 3 ·2H 2 O microcrystal with various morphologies. FeCl 3 ·6H 2 O and NH 4 H 2 PO 4 were employed as raw materials without any surfactant assistance to synthesise Fe 5 (PO 4 ) 4 (OH) 3 ·2H 2 O microcrystal by one‐step hydrothermal method. The effect of reactant concentration on the morphology of the product was systemically studied. The results indicate that with increasing concentration of reactants, morphology of the product could converted from dendrite shape to flower shape and sphere. The corresponding FePO 4 with various morphologies was also easily prepared by heating the Fe 5 (PO 4 ) 4 (OH) 3 ·2H 2 O precursor at the optimum temperature. This work provides an effective method to synthesise Fe 5 (PO 4 ) 4 (OH) 3 ·2H 2 O and FePO 4 microcrystal with various morphologies which could meet the demands of lithium‐ion battery material and catalyst material.
