High-Temperature Interaction in the ZrSi2–ZrSiO4 System and Its Mechanism

详细

The physicochemical interaction in the ZrSi₂–ZrSiO₄ system at temperatures higher than 1620°C under the conditions of molecular oxygen deficiency is established and experimentally confirmed. Elemental silicon is reduced simultaneously with the oxidation of zirconium to the thermodynamically stable ZrO₂ phase. The mechanism and steps of the interaction processes are proposed.
