characterization and synthesis of hardystonite (ht) as a novel nanobioceramic powder

objective(s): hardystonite (ht) has been successfully prepared by a modified sol-gel method. we hypothesized thatnano-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 characterized by means of scanning electron microscopy(sem), x-ray diffraction (xrd), transmission electron microscopy (tem) and fourier transform infrared spectroscopy(ft–ir). 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.
