Abstract

The equilibria in the Al(1)-Cl₂(g) system have been studied at temperatures from 600 to 1300 K using a transpiration reactor. The equilibria considered were those among Al(s or l)-Al(g)-Cl₂(g)-AlCl(g)-AlCl₂(g)-AlCl₃(g)-Al₂Cl₆( g). The standard Gibbs energies of formation for the AlCl(g) and AlCl₂(g) species at these temperatures have been determined simultaneously, where these subchloride species coexist in appreciable quantities with the AlCl₃(g) and Al₂Cl₆(g) species in the gas phase at these temperatures, as follows: AlCl(g): ΔG_f·AlCl·T ⁰(600-900 K) = -76.6-8.05×10^-2T; ΔG_f·AlCl·T ⁰(1000-1300 K) = -91.9-6.41×10^-2T AlCl₂(g): ΔG_{f·AlCl(2)·T} ⁰(600-900 K) = -319-3.35×10^-2T; ΔG_{f·AlCl(2)·T} ⁰(1000-1300 K) = -335-1.65×10^-2T.
