摘要：

Data are presented that support the explanation of the 980 degree 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 aluminum/octahedral aluminum ratio, as evidenced by IR spectroscopy. The so-called mulite peak at 1250 degree 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.
