Abstract

The influences of inactive, flowing atmospheres (noble gases, nitrogen, carbon dioxide, synthetic air) and vacuum (10-2 and 10-5 torr) on the thermal decompositions of inorganic and organic substances are discussed on the basis of literature and experimental data. The fact that it is necessary to use a controlled gas atmosphere from the preparation of samples up to the study of the mechanisms of solid-state reactions is proved by several examples. Results are presented relating to the decompositions of silver(I) oxalate, potassium acetate, and a natural mixture of clays and alkaline earth metal carbonates, to the behaviour of β-manganese(IV) oxide and to the low-temperature dehydroxylation of kaolin, as studied especially by TG, DTG, DTA and MS methods.
