THERMALLY-INDUCED REACTIONS OF SOLIDS - ISOKINETIC RELATIONSHIPS OF NONISOTHERMAL SYSTEMS

Reactions of solids exposed to non-isothermal heating reveal diverse i sokinetic relationships (IKR). Some of these effects are exclusively i nherent to nonisothermal reactions of solids. The present paper briefl y surveys the most commonly encountered IKRs, classifying them into tw o main types:'false' and 'true'. The origin of 'false' IKRs, their mea ning and their possible practical application, based on the related is okinetic temperatures are elucidated. For 'true' IKRs emphasis is put on the correlation between the experimentally found isokinetic tempera ture, characteristic bands in infrared spectra, and the mechanism of p rocess. Theoretical considerations are illustrated by experimental exa mples for reactions of inorganic substances and polymers.
