The authors reported the data found by FT-IR spectroscopy, ultrasonic velocities, DTA and, optical investigations of (50-x) Na₂B₄O₇–30PbO₂–20SiO₂–xTiO₂ where x = (0, 10, 20, 30, 40, and 45) mol%. The structure changes of these glasses will be studying by FT-IR spectra. The mechanical properties have been associated with the results of FT-IR spectra. It was noted that the ultrasonic velocities, elastic-moduli, and density physical properties of these samples increased. The obtained results will discuss in terms of structural changes due to the addition of TiO₂. Optical feature spectra are recorded at room temperature. The Urbach’s energy (E_u) of the prepared samples has been estimated. Polarizability and basicity of the prepared glasses according to the refractive index and optical bandgap have been investigated. The nature of the produced glasses and glass–ceramics was examined by (XRD) analysis.

作者报告了通过FT-IR光谱，超声速度，DTA和（50-x）Na ₂ B ₄ O ₇ –30PbO ₂ –20SiO ₂ –xTiO _2的光学研究发现的数据，其中x =（0，10，20 ，30、40和45）mol％。这些玻璃的结构变化将通过FT-IR光谱研究。机械性能已经与FT-IR光谱的结果相关联。值得注意的是，这些样品的超声速度，弹性模量和密度物理性质均增加了。所得结果将讨论由于添加TiO ₂而引起的结构变化。在室温下记录光学特征光谱。乌尔巴赫能量（E_u）已准备好的样品已经过估算。已经研究了根据折射率和光学带隙所制备的玻璃的偏振性和碱性。通过（XRD）分析检查了生产的玻璃和玻璃陶瓷的性质。
