- Abstract
Objective(s): Hardystonite (HT) has been successfully prepared by a modified sol-gel method. We hypothesized that nano-sized (HT) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size (HT). Materials and Methods: The hardystonite nanopowder was prepared via a modified sol-gel method.Optimization in calcination temperature and mechanicalball milling resulted in a pure and nano-sized powder which was characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM) and fourier transform infrared spectroscopy (FTIR). Results: Pure (HT) powders were successfully obtained via a simple sol-gel method followed by calcination at1150 °C. Mechanical grinding in a ceramic ball mill for 6 hours resulted in (HT) nanoparticles in the range of about 32-55nm. Conclusion: Our study suggested that nanohardystonite (NHT) might be a potential candidate by itself as a nanobioceramic filling powder or in combination with other biomaterials as a composite scaffold in bone tissue regeneration.
