Experimental and computational studies of melting of the spinel phase in the Fe-Al-O ternary system

• The melting behavior of spinel in the Fe-Al-O system at high temperatures (1500-1800 degrees C) was studied by a combination of experimental and computational investigations. Differential thermal analysis (DTA) at ultra-high temperatures coupled with cooling traces on CO2 laser-heated levitated samples provided melting temperatures and the heats of fusion of (Fe,Al)(3)O-4 spinel phases. The experimental results are in fair agreement with the predictions using a published CALPHAD description and areas for modeling improvement are identified. New insights into the melting of defect spinel are provided.
