Abstract
The vaporizing species in the Al–Al2O3 system are identified mass spectrometrically. Intense ion currents of Al2O+ formed from gaseous Al2O are observed. At T = 1750°K ions formed from other gaseous oxides are at least 1000 times less intense than Al2O+. The appearance potential of Al2O+ is 7.7±0.2 ev. A thermodynamic treatment of gaseous Al2O gives for Al2O(g) = 2Al(g) + O(g), ΔH298 = 256±7 kcal.Keywords
