A complete literature review, critical evaluation of the available data and thermodynamic optimization of the phase equilibria and thermodynamic properties of oxide phases in SiO2-ZnO system at 1 atm pressure are presented. The molten oxide phase is described with an associate solution model. A set of optimised model parameters of all phases was obtained which reproduces all available and reliable thermodynamic and phase equilibrium data within their experimental error limits from 298 K to above the liquidus temperatures over the entire composition range. The created database of the model parameters can be used in the Gibbs energy minimization software to calculate the thermodynamic properties and the phase diagram sections of interest.
