dc.description.abstractBioactive Glass (Bg) Is A Material That Adheres To Tissues When Implemented In The Human Body Because Of Its Surface Reactive Properties. The Development Of Hydroxyapatite (Hap) Layer On Its Surface Is Basic Characteristic Of Bioactive Glass, Which Is Primarily Determined By Its Chemical Composition And Morphology. In Order To Develop Porous Bgs With Large Specific Surface Areas (Ssa), Surfactants Have Been Usually Utilized. However, Such Compounds Induce Micell Aggregation And Carbon Contamination. On The Other Hand, Acid Catalysts Have Been Utilised To Alter The Morphology Of Particles As Well As For Hydrolysis And Condensation Of Alkoxides In Sol-Gel Method. Most Inorganic Acid Catalysts Employed At High Concentrations (0.5-2 M) Leave Behind Numerous Residual Ions That Can Affect Bg Particles Hap Development As Well As Subsequent Cell Proliferation And Differentiation. In This Study, Hydrogen Peroxide (H2o2), A Carbon-Free And Highly Soluble Compound Was Used As A Poreforming Agent Instead Of Conventional Surfactants For The Synthesis Of Bg. The Hydrolysis And Condensation Reaction Also Executed Lower Concentrations (0.5 Mm) Of Citric Acid, An Organic Acid Catalyst. The H2o2 Untreated Bg (Bg0),1m H2o2 Treated Bg (Bg1),2m H2o2 Treated Bg (Bg2), And 3m H2o2 Treated Bg (Bg3) Were All Made Using The Sol-Gel Method. Thermal Stability, Phase, Surface Morphology, Chemical Composition, Constituent Composition, Pore Volume, Pore Size, And Specific Surface Area Were Analyzed Using Thermogravimeteric Analysis (Tga), X-Ray Diffraction (Xrd), Scanning Electron Microscopy (Sem), Fourier Transform Infrared spectroscopy (Ftir), Energy Dispersive X-Ray Spectroscopy (Eds), And Brunauer-Emmett-Teller (Bet) Respectively. Invitro Bioactivity Test Was Performed By Immersing Bg Powders In Simulated Body Fluid (Sbf) Solution And Hap Formation Was Analyzed. Also Invitro Biodegradability Test Was Performed By Immersing Bg Pellets In Sbf Solution And Weight Loss Was Analyzed For 30 Days. Finally, Invitro Bioactivity And Biodegradability Of The Bgs Were Correlated With H2o2 Concentration And Ssa. According To The Results, Bg Particles Treated With 2 M H2o2 Obtained A Larger Ssa Which Is 189.55 Cc/G And Exhibits Better Invitro Bioactivity And Biodegradabilityen_US
