Abstract

Titanium-doped and titanium-free lithium borate glasses were prepared using a quenching method and high-purity-grade chemical substances. Structural analysis was carried out by Fourier transform infrared (FT-IR) spectroscopy and mechanical measurement. The states of the produced glasses were examined by x-ray diffraction, and the density (ρ) and molar volume (V_m) were determined. The Makishima–Mackenzie model was applied for the prepared glasses. FT-IR confirmed that the concentration of [BO₄] was greater than that of [BO₃] structural units. These variations confirmed that the compactness of the lithium borate network increased as the concentration of (TiO₂/B₂O₃) increased. The longitudinal (v_L) and shear (v_T) velocities of the samples with varying concentrations of (TiO₂/B₂O₃) were found to increase, along with the elastic moduli. The thermal stability, energy gap, and refractive index of the prepared glasses increased as the concentration of (TiO₂/B₂O₃) was increased.

抽象的

使用淬火方法和高纯度化学物质制备了掺钛和不含钛的硼酸锂玻璃。结构分析是通过傅立叶变换红外（FT-IR）光谱和机械测量进行的。通过X射线衍射检查制得的玻璃的状态，并确定密度（ρ）和摩尔体积（V _m）。Makishima–Mackenzie模型用于准备的眼镜。FT-IR证实[BO ₄ ]的浓度大于[BO ₃ ]结构单元的浓度。这些变化证实了硼酸锂网络的致密性随着（TiO ₂ / B ₂ O ₃的浓度）的增加而增加。） 增加。发现具有不同浓度（TiO ₂ / B ₂ O ₃）的样品的纵向（v _L）和剪切（v _T）速度随着弹性模量的增加而增加。随着（TiO ₂ / B ₂ O ₃）的浓度增加，制备的玻璃的热稳定性，能隙和折射率增加。
