- Abstract
Samples of base calcium sodium borophosphate bioglasses doped with different amounts of zirconium oxide (ZrO2) were prepared via melt quenching technique. Synthesized samples of nominal composition xZrO2-45B2O3-(24.5-x)CaO-24.5NaO2-6P2O5 x = 0 (S0)—5 (S6) mol% was investigated using fourier transforms infrared (FTIR) spectroscopy and deconvolution analysis technique (DAT) was employed to investigate the variation of the four coordinated borons. X-ray diffraction (XRD) technique to approve the isotropic character of the prepared glasses. Density (ρ) of samples varied from 2.606 g/cm3 to 2.642 g/cm3 and molar volume (Vm) enhanced from 25.565 cm3.mol−1 to 26.649 cm3.mol−1. FTIR spectroscopy revealed that only reliable bands were considered and the (r2-value) of the regression was nearly 0.99. The maximum value of the difference between experimental and theoretical data not exceeds ± 0.015 from the normalized spectral data. The fraction of the four coordinated boron was slightly changed due to the addition of ZrO2 in the doping level. The decrease in the N4 values can be attributed to the structural changes combined with the conversion of BO4 to BO3 units.
