Thermodynamic Study on Rare Earth Vapour Complex:EuAl_3Cl_（12）

Thermodynamic study was carried out on the reaction EuCl_(3(s))+(v/2)Al_2Cl_(6(g))= EuAl_vCl_((3v)+3(g))byquenching experiments within 6 3 8 ～ 7 6 2 K and 0 . 0 3 ～ 0 . 1 4 MPa . The results suggested that theEuAl_3Cl_(12(g)) complex was the predormnant species. The equilibrium constants of the reaction were measured. The reaction enthalpy and entropy derived from the measurements were and
