Density And Thermal Expansion Calculation Of Silicate Glass Melts From 1000 Deg C To 1400 Deg C

The relation between the chemical composition and the density of silicate glass melts at temperatures of 1000 edge C to 1400 deg C was analysed statistically. The analysis was founded on all 140 to 260 available values in the SciGlass information system for compositions containing more than 40% mol silica, less than 40% mol boron oxide, varying amounts of Al2O3, Li2O, Na2O, K2O, MgO, CaO, PbO, and minor components. A model based on multiple regression was developed. The 95% confidence interval of the mean model prediction on the density was 0.5 to 3%.
