In this study, a glass system with multiple components was prepared using the melt quench technique, and various analyses and investigations were conducted. The results showed that these glasses possessed unique structures and properties, suggesting their potential applications in the field of biomedicine.
Glassy system of composition xLi(2)O.3P(2)O(5).21Na(2)O.26CaO.(50-x)B2O3 (x = 0, 1, 2, 3 and 4 mol%) was prepared by melt quench technique. X-ray diffraction, Infrared spectroscopy and Field emission scanning electron microscope with Energy dispersive spectroscopy were conducted to identify crystalline phase formation in glass powder and to study morphologies. The deconvoluted IR absorption spectra of synthesized samples, were analyzed to examine the structural rearrangements in the glass matrix before and after immersing in the phosphate solution. Optical band gap, Urbach energy and refractive index of the synthesized compositions were also obtained from the analysis of optical absorption spectra to examine the semiconducting behavior. The effects of the treatment in phosphate buffer solution for 12 days on crystallization & structural properties of these glasses were systematically investigated. The dependence of physical parameters on the glass composition suggested a variation in the number of non-bridging oxygen with Li2O content. Morphological and structural study alongside a possibility of hydroxyapatite formation suggests the biomedical applications of these materials.
