Nanocrystallinity induced by heating

Abstract

Samples of akaganeite (β-FeOOH) and goethite (α-FeOOH) have been studied after heating at various temperatures up to 800 °C. X-ray diffraction and Mössbauer spectroscopy measurements showed that slightly below the temperatures at which the samples transform to hematite (α-Fe2O3) the oxyhydroxide phases become nanocrystalline.
