The authors reported the data found by FT-IR spectroscopy, ultrasonic velocities, DTA investigations of 5Al2O3 – 25Li2O – (70 − x) P2O5 – x TiO2, (0 ≤ x ≤ 25 mol%) of the prepared glass samples. From FT-IR spectroscopy has been indicated the titanate doped phosphate glasses increase the produce of non-bridging oxygens. By ultrasonic velocities has been indicated that these velocities are decreased as well as elastic-moduli and density by the concentration of titanate. This behaviour due to decreasing the density, cross-link density, and increase in molar volume. By DTA the values of (Tg), (Tc) and (Tp) decrease this is due to a decrease the bond strength. A parent glass–ceramics of these glasses have been prepared, and investigate by XRD and SEM. The parent glass–ceramic of these glasses have been prepared and investigate by XRD. Li2P2O6 (lithium orthophosphate) crystalline phase is showed in glasses-free titanate and transformed into LiPO3 in glasses containing titanate. The surface morphology of glass–ceramic has been checked by scanning electron microscope and showed a nearly unchanging surface in glasses-free titanate and large interstitial pores in glasses containing titanate.
