In this study, a glass system with specific components was fabricated using melt-quenching techniques. The research investigated the relationship between elastic properties and BaO content, with experimental and theoretical comparisons. Additionally, changes in glass density, molar volume, elastic moduli, and their effects on material properties were explored.
The glass system 22SiO(2)- 23Bi(2)O(3)-37B(2)O(3)-13TiO(2)-(5-x) LiF- x BaO,(0 <= x <= 5)mol.%. was fabricated using melt-quenching techniques. X-ray diffraction and ultrasonic techniques were used to characterize the glasses. X-ray diffraction patterns were used to prove that fabricated glasses are amorphous. The impacts of incorporating BaO on the composition dependence of the elastic characteristics of fabricated samples were explained. Density of the manufacture glasses increment, and molar volume reduced. The elastic moduli were investigated experimentally then compared using theoretical arguments. Makishima - Mazinize model were used to determine the elastic moduli theoretically for fabricated samples. Elastic moduli increase with BaO, and experimental and theoretical elastic moduli are in good agreement. Deviation values between elastic moduli (both experimentally and theoretically) were estimated. All the experimental variations values of elastic moduli of fabricated glasses were increment as BaO increased. Latent heat of melting, diffusion constant, and Gruneisen factor have been used to link the mechanical and thermodynamic characteristics of manufactured glass.
