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

Abstract

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