Thermodynamic investigation of the AlNC and AlCN isomers by Knudsen cell mass spectrometry
Equilibria involving the isomers AlNC and AlCN above a mixture of aluminum nitride, graphite, and gold contained in a graphite Knudsen cell were investigated with a mass spectrometer. The enthalpies of formation, Delta(f)H(0)(o), and of atomization, Delta(a)H(0)(o), in kJ mol(-1), for AlNC and AlCN, were derived as 281.3+/-14 and 303.8+/-14, and as 1228.1+/-15 and 1205.6+/-15, respectively.
