Comparative Studies on Spectroscopic and Crystallization Properties of Al2O3 -Li2O- B2O3-TiO2 Glasses

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.
