Bismuth barium titanate glasses have been synthesized by conventional melt quenching technique. X-Ray Diffractograms confirmed the glassy nature of the prepared samples. Various parameters such as density, molar volume, Oxygen packing density (OPD), molar refractivity, molar polarizability, metallization criterion, refractive index and reflection loss have been calculated for understanding the physical and optical characteristics of prepared glasses. A perusal of Differential thermal analysis (DTA) and oxygen packing density (OPD) values confirmed that there is an increase in glass transition temperature (T_g) with increasing BT (BaO-TiO₂) content. The analysis of Fourier-transform Infra-Red (FTIR) and Raman spectra clearly confirmed that the glass network mainly comprises of [TiO₄], [TiO₅] and [TiO₆] units which play a significant role as the network formation, network intermediate and network modifier respectively. A non-linear variation of optical band gap energy with the increase in BT (BaO-TiO₂) content has been recorded and the same has also been confirmed from the Urbach energy calculations and metallization criterion of the prepared glass samples. The electronegativity and electronic polarizability values revealed the ionic character of the glass samples.

钛酸铋钡玻璃已经通过常规的熔融淬火技术合成。X射线衍射图证实了所制备样品的玻璃状性质。为了理解所制备玻璃的物理和光学特性，已经计算出各种参数，例如密度，摩尔体积，氧堆积密度（OPD），摩尔折射率，摩尔极化率，金属化标准，折射率和反射损耗。仔细研究差热分析（​​DTA）和氧堆积密度（OPD）值可确定，随着BT（BaO-TiO ₂）含量的增加，玻璃化转变温度（T _g）也会增加。对傅立叶变换红外（FTIR）和拉曼光谱的分析清楚地证实，玻璃网络主要由[TiO₄ ]，[TiO ₅ ]和[TiO ₆ ]单元分别起着网络形成，网络中间物和网络改性剂的重要作用。记录了随着BT（BaO-TiO ₂）含量的增加，光学带隙能量的非线性变化，并且根据制备的玻璃样品的Urbach能量计算和金属化标准也已确认了这种变化。电负性和电子极化率值揭示了玻璃样品的离子特性。
