By the substitution of Al2O3 and B2O3 for SiO2 of the glass network former, the structural and thermodynamic properties of aluminosilicate glass were investigated. Judged by Raman spectra, the bridging vibration Si-Ob increased with the Al2O3/SiO2 substitute. And the total non-bridging vibration Si-Onb decreased, indicating the enhancement of the structure compactness. While for B2O3/SiO2 substitute, the vibration at around 1010cm-1 and the bridging vibration Si-Ob in Q4 unit both decreased and the structure got loosened. Based on the study of the structure of glass, the thermodynamic properties such as viscosity, coefficient of the linear thermal expansion, high-temperature resistance, strain point, annealing point and softening point, as well as density and elastic modulus were investigated. With the enhancement of thermodynamic properties requirements, the difficulty in industrialized manufacturing was increased. In this paper, glass composition of sample 4 was suitable for floating process production.
