Abstract
To use the gas solubilities reported in the literature for binary or ternary silicate or borate melts to predict values for industrial glass melts, a basicity number concept was developed. Acidic values derived by cation-oxygen bond strengths multiplied by the mole fractions of the glass oxides were used to form a scale of basicity numbers for glass melts. The origin of this scale is the basicity number of boron oxide. This basicity number concept was successfully applied to gas solubility values for H2O, CO2, and SO2 in binary and ternary glass melts and to the solubility of oxygen in glass melts with multivalent ions, such as iron, arsenic, antimony, cerium, chromium and manganese.
