Impact of magnetic field on the mineralization of iron doped calcium phosphates
Iron doped calcium phosphate having different morphologies has been synthesized using gel medium and the change in morphology caused due to the incorporation of iron in the presence and absence of magnetic field have been studied. The oriented dendritic growth of brushite crystals were observed in the presence of magnetic field. The plate like hydroxyapatite (HAp) was converted into needle like morphology on application of magnetic field. Various functional groups corresponding to HAp and dicalcium phosphate dihydrate (DCPD) were observed in the FTIR and Raman spectrum. Presence of HPO42- in the crystals grown in the absence of magnetic field has been confirmed from FTIR and Raman results. Nanoroughness of the crystals was also seen to increase on applying a magnetic field of the order of 0.1 T. Magnetic field makes the samples devoid of HPO42- phase and also limits the concentration of iron incorporated thus, leading to a change in the morphology.
