Oxidation of tungsten in the W-Al 2 O 3 system at ...

Feb 14, 2011· We examine chemical reactions that lead to the oxidation of tungsten in the W-Al2O3 system at T = 2350–2500 K and p = 1–105 Pa. The results indicate that, for p ≥ 10 Pa, tungsten oxidizes through reactions with both Al2O3 vapor and dissociation products (Al2O2, Al2O, AlO2, and AlO). For p ≤ 10 Pa, oxidation is due to direct reaction of tungsten with O and/or O2.
