Bone is a real nanocomposite which is formed of two organic (collagen) and inorganic (nano-hydroxyapatite) phases. The construction of new composite as bone and tissue substitute is one of the notable topics in bone and tissue engineering. In this study, nano-hydroxyapatite and its composites, including 2.5, 5 and 7.5% (w/v) zeolite were synthesized. XRD and FTIR tests were utilized to investigate the crystal structure and determine the functional groups, respectively. Considering the XRD test, nano-composite of hydroxyapatite-zeolite has more crystallinity compared to the pure hydroxyapatite. Finally, according to the results, the use of 7.5% zeolite for the synthesis of nano-composite of hydroxyapatite-zeolite is recommended as a bone substitute.
