Review of Micro-Particles of Hydroxyapatite Nanoparticles by Ball Milling

Hydroxyapatite (HA) is the most important bioactive ceramics because of biocompatibility and structural similarity to the mineral part of bones and teeth of broad clinical application in the field of dentistry, orthopedic and coatings are Biomaterials. The aim of this study was to construct nano-hydroxyapatite micro particles using calcite, silica and zinc oxide using ball milling, powder, these three compounds, crushed and then molded into a cylindrical shape, pressed and put in oven a. The review ray diffraction X (XRD) suitable for milling, baking time and temperature samples obtained. The graph of the analysis of the samples was compared with HS. According to the results, the sample A with 10 hours of milling, temperature and heating time of 2 hours C˚ 1100, most of the other samples produced Hardstvnyt product
