Survey and Evaluation of Diopside Nanostructure (DSN) Bioactivity in Biomedical Application

Diopside (DS) is a monoclinic pyroxene mineral with composition MgCaSi2O6. Lately,diopside (DS) has beenintroduced as a bioceramics due to its best bioactivity and biocompatibility. It has a good strength andtoughness than those of hydroxyapatite (HT). In this project, bioactivity of diopside (DS) powder wereevaluated and investigated. For synthesized of diopside (DS) powder, magnesium (Mg), calcite (CaCO3)and nano silicium (SiO2) powders was mechanically activate for different times. After that, the preparedpowders were blended with ammonium chloride (NH4Cl) and put on various temperatures. In this part, forsurvey of bioactivity evaluation, the obtained dioside (DS) powders were pressed and immersed in Kukobosolution (SBF)The results indicated that nano-struacture diopside powder with crystalline size is 40 nm.The apatite formation ability, bioactivity and better mechanical behavior make it a good candidate in boneimplant materials and open new insights in biomedicalapplications.
