ABSTRACT: In this study, melting temperature modeling was carried out for SiO2-Na2O-CaO ternary vitrifiable oxide mixtures, based on literature data and the results of our experimental tests. The aim of this modeling is to determine a mathematical model for predicting the melting temperature of vitrifiable mixtures composed of the oxides of silicon, sodium, and calcium using the proportions of these to produce silica glass. First, the mathematical approach with first-order, second-order, synergistic third order and full third-order models was implemented. Secondly, the experimental approach was used to validate a model for estimating the liquidus of SiO2-Na2O-CaO ternary mixtures through melting tests. The accuracy evaluated with the coefficient of determination (R2) of the full third-order model selected is 0.9908. Based on the liquidus model obtained, a ternary diagram was proposed to facilitate the determination of temperatures as a function of ternary mixture compositions. In addition, an algorithm has been developed based on this model to facilitate its use.
