Bio behavioral, elastic, structural and spectroscopic aspects of CZPT glasses

The Calcium Zinc Phospho Titanate (CZPT) glasses with the composition CaF2–ZnO–P2O5:TiO2 are synthesized. The prepared glasses were found to possess a bioactive nature after immersing in simulated body fluid (SBF) for the various durations at physiological conditions and the pH values/dissociation rates are measured. XRD, SEM, and EDAX studies are carried out for the prepared glasses. The influence of coordination states of titanium ions on these glasses was studied by analyzing the DTA, FTIR, Raman, OA, and ESR spectral studies and the mechanical properties by analyzing the elastic parameters of prepared glasses. The coexistence of trivalent and tetravalent titanium ions is established by studying various structural and spectroscopic aspects. The FTIR and Raman spectral analysis of present glass samples after deconvolution indicates the presence of both Ti3+ (octahedral) and Ti4+ (tetrahedral and octahedral) ions. The conversion rate of Ti4+ ions into Ti3+ ions was based on the content of dopant, TiO2 in the glass matrix.
