BS>The vapor pressure of Al₄C₃ has been measured in the region from 1500 to 1800 °K by means of the Knudsen effusion method and of a torsion method. DELTA H^o at 1600 °K was calculated for the reaction Al₄C₃(s) yields 4Al(g) + 3C(s) hy means of the second law and the third law, and respective values of 89 (±3) kcal/mole Al and 87 (±3) kcal/mole Al were obtained. The results indicate carbon content of no more than 2% in the vapor when aluminum carbide is dissociated at 1600°K.
