Abstract	This study explores the synthesis and characterization of Bioglass 45S5, a bioactive material with significant application in bone regeneration and biomedical implants. The Bioglass 45S5 was synthesised using the sol – gel method with an acid catalyst (nitric acid), ensuring controlled structural formation. The synthesised material was subjected to X – ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR), to confirm its composition, crystallinity and thermal stability. XRD analysis identified Na₂Ca₂Si₃O₉ (Combeite) with an Orthorhombic structure and CaSiO3 (wollastonite) with a monoclinic structure, with crystalline size 54.8 nm (combeite) and 83.3 nm (Wollastonite), calculated using Scherrer’s equation. The FTIR spectra confirmed the presence of silicate and phosphate functional groups essential for bioglass. The findings suggest theat the synthesized Bioglass 45S5 exhibit highly controlled crystallinity, making it a promising material for biomedical applications such as bone regeneration and implant coatings.
