Mechanical processing of γ-Fe2O3

Inorganic Materials Aims and scope

Abstract

We have studied the effect of mechanical processing of γ-Fe2O3 with the use of a planetary ball mill on the characteristics of resulting powders: phase composition, crystallite size, particle size, and specific surface area. The results demonstrate that the mechanical processing of γ-Fe2O3 leads to the γ-Fe2O3 → α-Fe2O3 phase transition. The formation of α-Fe2O3 is shown to be accompanied by considerable changes in the specific surface area and particle size of the powder material.
