Web7 apr. 2024 · Indeed, the possibility to form these oxides can be predicted by the Ellingham diagram for oxygen, and the Ellingham diagram was established by calculating the equilibrium partial pressure of the oxidation reaction [8]. The order of the Gibbs energy of formation for the involved oxides is SiO 2 WebAn Ellingham diagram is a plot of 6G (change in Gibbs free energy) versus temperature, which, for our purposes, would be a temperature in a continuous furnace by zone or in a batch furnace by time in the cycle.
