Equilibria in the Fe2(SO4)3/Fe2O3/SO3 system

W. David Halstead  and  James W. Laxton  

Abstract

The pressures of SO3 which exist in equilibrium with ferric sulphate have been measured in the temperature range 740 to 975 K by static and dynamic techniques. The overall equilibrium may be described by the two equations Fe2(SO4)3⇌Fe2O3+ 3SO3, 2SO3⇌2SO2+ O2 The equilibrium SO3 pressures above partially sulphated samples prepared from α-Fe2O3 follow the equation log10(PSO3/N m–2)= 14.18 ± 1.39 –(0.95 ± 0.11)K//T× 104 while for partially sulphated samples prepard from γ-Fe2O3 the equation log10(PSO3/N m–2)= 13.17 ± 1.10 –(0.91 ± 0.09)K//T× 104 holds. The latter equation is in good agreement with previously published equilibrium pressure data.
