Abstract
The reduction of dense magnetite samples in H2/H2O and H2/N2 gas mixtures between temperatures of 723 and 1373 K has been investigated. A detailed study of partially reduced samples using conventional metallographic and scanning electron microscopy (SEM) techniques has enabled the conditions for the formation of a number of different product microstructures to be clearly defined. The reaction mechanisms involved in various continuous and discontinuous growth processes are discussed.
