Abstract

The thermal decomposition of Fe2(SO4)3 in air has been investigated using transmission Mössbauer spectroscopy, CEMS and X-ray powder diffraction. The hexagonal α-Fe2O3 and cubic β-Fe2O3 with spinel structure have been identified as products of the decomposition. The influence of the Fe2(SO4)3 particle size on the yield of β-Fe2O3 in the final product is pointed out and discussed. The size of particles and the calcination temperature are the most important kinetic factors determining the phase composition (β-Fe2O3/α-Fe2O3) of iron (III) oxide.
