Structural Properties of Mesoporous Borosilicate Bioactive Glass

A series of mesoporous borosilicate bioactive glasses (MBBG) with compositions of (x)B2O3-(80-x) SiO2-15CaO(2)-5P(2)O(5) where x = 0, 5, 10, and 15 mol% are functionalized using a combination of the sol-gel method and evaporation-induced self-assembly (EISA) process, along with a calcination temperature of 600 degrees C at 7 hours. The amorphous nature of the glass is determined using an X-ray diffractometer (XRD) and, the structural properties are characterized using a Fourier Transform Infrared (FTIR) spectroscopy in the range of 400 to 4000 cm(-1). XRD spectra confirm that all the glass samples are amorphous. FTIR spectrum exhibited three major bands attributed to identifying chemical bonds in a molecule by producing an infrared absorption spectrum with varying percentages of boron oxide. The appearance of three distinct primary bands corresponding to the Si-O- Si bond vibration modes. The B-O symmetric stretching vibrations refer to theband at 1400 - 1500 cm(-1).
