In the molten state, experimentally constrained models show that the iron ions are coordinated to 5 oxygen ions on average. [19], Fe3O4 is an electrical conductor with a conductivity significantly higher (X 106) than Fe2O3, and this is ascribed to electron exchange between the FeII and FeIII centres. [18] This effect has been extensively investigated and whilst various explanations have been proposed, it does not appear to be fully understood. Fe 2 O 3 is the main source of iron in steel and iron industry, and it is used to produce some alloys. It is an ingredient in thermite which is used for cutting steel.
