Effect Of Silver On Sol-Gel Derived Bioglass System

A sol-gel derived bioactive glass (BG) with the composition of 55% SiO₂ - 4%P₂ O₅ -22% Na₂ O-19% CaO (wt %) was synthesized using tetraethoxysilane (TEOS), 0.1M nitric acid (HNO₃ ), Triethyl phosphate (TEP), Calcium nitrate tetrahydrate(Ca(NO3)2.4H2O), Sodium nitrate(NaNO₃ ). Silver nitrate(AgNO3) w...
