Methods Combined with DTAatus consists of an X-ray apparatus with a sample holder suitable for high-temperatures, which serves simultaneously as a DTA furnace combined with the remaining parts of a DTA apparatus. The method of . makes it possible to identify reaction products with a short existence that are only stable over a small range of temperature.

Zeolitesed. Most of the zeolites lose their water below 400° C (see Table 25). Only laumontite, chabasite and the minerals of the natrolite group (natrolite, scolezite, thomsonite) dehydrate partly between 400 and 600° C, so demonstrating that a part of the water has been structurally bound more effectively than the water of the channels.

Borates, Phosphates, and Arsenates dehydration in several steps between 90 and 580° C. Endothermic effects between 600 and 780° C reflect melting of the substances, exothermic effects between 600 and 800° C the reformation of a crystal structure (see Table Hand Fig.28).
