Calcium phosphate in the presence of cobalt ions were mineralized using gel technique. The presence of cobalt in the gel medium enhances the growth of di-calcium phosphate crystals and it is found to be concentration dependent of the dopant. The crystals were modified from platy to dendritic on increasing the cobalt concentration. The XRD pattern confirms the phase of the crystals to be DCPD with variation in the peak intensity. The FT-IR spectrum confirms the presence of functional groups such as stretching and bending vibrations P-O. The presence of cobalt in the gel medium promoted the formation of apatite like structures on the surface of the DCPD crystals. The presence of elements (Ca, P, O and Co) in the crystals was confirmed through EDX analysis. The formation of apatite in an additives free medium like SBF solution suggests that cobalt incorporated DCPD is highly bioactive and could be suitable for the preparation of bone cements.
