Abstract The construction of thermodynamic stability diagrams for the Fe-Cr-Al system is discussed. The constructed diagrams are used to predict materials behavior at coal gasifier oxygen and sulfur potentials. Experiments are run to compare predicted results with experimental observations. Powder mixtures of FeS, Cr2O3, and Al2O3 are used to observe the formation of the iron-chromia and iron-alumina spinels. The spinels are observed at both 871 and 982° C. The formation of an alumina spinel is observed only on the Fe-10Al alloy, whereas no iron-chromia spinel is found on the Fe-Al-Cr alloys.
