TIO2 DOPING EFFECT ON SHORT RANGE ORDER OF CAO•P2O5 GLASS MATRIX. Authors: M. MAIER, R. CICEO-LUCACEL. |

Abstract: Local order of ternary titanium-calcium–phosphate glasses prepared by classical melting method was characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier transform infrared (FTIR) and Raman spectroscopy. XRD results support the vitreous state of the samples and SEM analysis indicates no phase separation tendency. FTIR and Raman data reveal that the local network structure mainly consists of Q1 and Q2 tetrahedrons connected by P-O-P linkages. A gradual depolymerization of the phosphate chains was observed with the addition of the titanium dioxide.
Keywords: calcium-phosphate glasses, titanium doping, XRD, FTIR, Raman analyses. |
