Bredigite Nanostructure (BRN) is a calcium silicate mineral with composition Ca7MgSi4O16. Lately, Bredigite Nanostructure (BRN) has been introduced as a bioceramic materials due to its best bioactivity and biocompatibility. It has a good strength and toughness than those of hydroxyapatite (HA). In this project, bioactivity of Bredigite Nanostructure (BRN) powder were evaluated and investigated. For synthesis of BRN powder, Magnesium nitrate hexahydrate (Mg (NO3)2.6H2O), Calcium nitrate tetra hydrate (Ca (NO₃)₂ .4H₂O) powders and Tetraethyl ortho silicate liquid (TEOS) was used and using Sol-Gel process. In this part, for survey of bioactivity evaluation, the BRN synthesized powders were pressed and sintered then immersed in Kukobo solution (SBF) for 28 days at 37 °C in incubator. The results indicated that nano-struacture bredigite powder with crystalline size is 45 nm. The apatite formation ability, bioactivity and good mechanical behavior make it a good candidate in bone implant materials and open new insights in biomedical engineering.
