Fernando D, et al. - The effect of order of network modifying precursor addition on the textural properties of sol–gel derived bioactive glasses was investigated via switching the order of network modifying precursor (calcium acetate monohydrate and sodium acetate anhydrous) addition for a fixed composition of bioactive glass (75SiO₂:5CaO:10Na₂O:10P2O₅). As per results, the order of precursor addition was noted to have influence on the porosity of these glasses. This simple and straightforward route adaptation to the preparation of bioactive glasses seemed to have value for enhancing the textural properties of the existing and novel composition of bioactive glasses and thus accelerating their bioactivity.
