The conventional technique has been used to prepare a quaternary glass based on the chemical composition 5Al2O3-\((10+x)\) Li2O-\((70 - x)\) B2O3-15TiO2 \(:(0\le x\le 25)\) mol.%. The Fourier transform infrared spectrometer spectra were investigated for the structural change of these glasses. Ultraviolet spectroscopic at ambient temperature of the investigated glass system. The optical bandgap and refractive index of these glasses were decreased, while Urbach energy was increased. The polarizability and basicity of these glasses have been established. To demonstrate the influence of titanium oxide on dispersion parameters, these glasses were applied. Under controlled heating, the glass–ceramic was prepared and investigated using X-ray diffraction and mechanical characteristic. Glass–ceramic surface morphology has been examined by scanning electron microscope.

Al2O3-Li2O-B2O3-TiO2玻璃的光谱和结晶性能对比研究

常规技术已用于制备基于化学成分 5Al 2 O 3 - \((10+x)\) Li 2 O- \((70 - x)\) B 2 O 3 -15TiO 2 的四元玻璃\(:(0\le x\le 25)\)摩尔%。研究了这些玻璃的结构变化的傅里叶变换红外光谱仪光谱。研究玻璃系统在环境温度下的紫外光谱。这些玻璃的光学带隙和折射率降低,而 Urbach 能量增加。这些玻璃的偏振度和碱度已经确定。为了证明氧化钛对色散参数的影响,应用了这些玻璃。在受控加热下,制备玻璃陶瓷并使用 X 射线衍射和机械特性进行研究。微晶玻璃表面形态已通过扫描电子显微镜进行了检查。
