Bredigite (BG) as a novel nanobioceramic powder; investigation and characterization

Document Type : Research Paper


In this project, Bredigite (BG) has been successfully prepared by a modified sol-gel method. Optimization in calcination temperature and mechanical ball milling resulted in a pure and nano-sized powder which characterized by means of X-ray diffraction; scanning electron microscopy, transmission electron microscopy and Fourier transform infrared Spectroscopy. We hypothesized that nano-sized Bredigite (BG) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size Bredigite (BG). Accordingly, we used the unique advantage of nanotechnology to improve novel nanobredigite (NBG) particles as a potential candidate for bone tissue regeneration whether as a peri-implant filling powder or in combination with other biomaterials as a composite scaffold.
