THERMALLY INDUCED REACTIONS OF SOLIDS: ISOKINETIC RELATIONSHIPS OF NON-ISOTHERMAL SYSTEMS

Reactions of solids exposed to non-isothermal heating reveal diverse isokinetic relationships (IKR). Some of these effects are exclusively inherent to nonisothermal reactions of solids. The present paper briefly surveys the most commonly encountered IKRs, classifying them into two main types:'false' and 'true'. The origin of 'false' IKRs, their meaning and their possible practical application, based on the related isokinetic temperatures are elucidated. For 'true' IKRs emphasis is put on the correlation between the experimentally found isokinetic temperature, characteristic bands in infrared spectra, and the mechanism of process. Theoretical considerations are illustrated by experimental examples for reactions of inorganic substances and polymers.
