Abstract
Hydroxyapatite (HA) is considered to form major component of bones and teeth. Synthesis of hydroxyapatite (Calcium phosphate, Ca10(PO4)6(OH)2) was carried out to produce nano powders. The size and shape of nano particles was controlled during synthesis by using templates of Cetyl Trimethyl Ammonium Bromide (CTAB). A cationic surfactant, CTAB creates micellar structures which would act as nano reactors for the synthesis of nano scale HA. Yield of the final product has also been examined by varying the surfactant concentration. X-ray diffraction data revealed characteristic peaks of HA, where a predominantly hexagonal lattice structure could be deduced. FTIR was used to observe the various chemical groups present in the product. Scanning electron microscope was used for the characterization of nano particles.
