Abstract Data are presented that support the explanation of the ∼980° C differential thermal analysis (DTA) exotherm of kandites in terms of transitional mullite (premullite) formation. The evolution of this material towards final 3∶2 mullite takes place with change in the tetrahedral aluminium/octahedral aluminium ratio, as evidenced by IR spectroscopy. The so-called mullite peak at 1250° C is shown to disappear when soaking experiments are carried out at lower temperatures, indicating that it is an effect of the dynamical character of DTA techniques.
