Crystallisation of hydroxyapatite nanocrystals under magnetic field

Crystallisation of hydroxyapatite (HAp) was studied in the presence of low magnetic field. The magnetic field favoured the formation of hydroxyapatite. The number of spherulites in the Lisesegang rings increased in the presence of magnetic field and that might be due to the acceleration in the diffusion of the reactants. The major plane of brushite crystals, which were formed along with HAp were found to orient perpendicular to the direction of the applied magnetic field. The crystals were also further characterised by XRD, SEM, FT-IR and DSC analyses.
