Реферат:
The evolution of the microstructure of α-Fe2O3 derived from synthetic α-FeOOH in a wide temperature range (400–1100 °C) has been systematically investigated using X-ray powder diffractometry and transmission electron microscopy. It was found that during the dehydration of α-FeOOH at 400 °C the α-Fe2O3 structure with a small amount of residual OH groups is formed. After heating at 500 °C the specimen has been shown to possess a stoichiometric composition. Further heating to 900 °C causes the gradual disappearance of the planar faults observed in low temperature specimens, followed by the formation of the (100) twins and surface steps enriched by potassium, chlorine and aluminium impurities.
