Phase And Structural Characterization Of Phosphate-Tellurite Crystalline Materials

Phosphate-tellurite crystalline materials containing titanium and aluminum oxide as well as a tellurite crystalline material containing lithium, barium and aluminum oxide were synthesized and investigated by X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy. XRD analysis shows peaks specific to the crystalline phases Al(PO3)(3) and TiP2O7. FTIR analysis revealed absorption bands specific to the bending and stretching vibration modes of the phosphate and tellurite crystalline networks.
