Notes:
The wettability of binary and ternary glasses belonging to SiO2–Al2O3–ZrO2 diagram has been studied using the sessile drop technique at 1750° and 1800°C. The ternary SiO2–Al2O3–ZrO2 (90–5–5 wt%) glass has proved to be well appropriated as a molybdenum oxidation barrier coating. The addition of 5 wt% of MoO2 slightly improves its wettablity at higher temperatures without affecting its oxidation barrier properties. The Mo comes into the glass network as a mixture of Mo5+, Mo4+, and Mo6+. After oxidation at 1000°C in oxygen atmosphere, the molybdenum remains in the glass network as Mo6+.
