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...

| description | 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) with different composition (2%, 5% and 8%) was added into the bioglass using the same method. All three samples were compared with silver free bioglass. Calcination process then performed on the samples at 700°C for 5 hours. After calcined, it can be observed that BG pellets that contained 5% and 8% silver burst in the middle part where bubbles like shaped can clearly be seen. The same samples have been calcined in powder form under the same temperature. But resultant with the same result. Bioglass sample with 8% silver also have the highest porosity percentage. For bioactivity test, the formation of apatite layer occurred the most on the surface of samples with highest silver content after soaking in SBF solution for 3, 7 and 14days compared to the other samples. Thus, additioning silver into the bioglass structure successfully enhanced the properties of bioglass. |
