Thermoanalytical examination under quasi-isothermal—quasi-isobaric conditions

Abstract The review begins with a short introductive survey on the history of the development of quasi-static measuring techniques. Thereafter, the authors give a detailed description of the measuring principles and theoretical fundamentals of the methods developed by themselves, of the so-called quasi-isothermal—quasi-isobaric (Q-TG and Q-TD) technique as well as of the simultaneous Q-TG/Q-DTG/Q-DTA and Q-TG/Q-TGT methods. Using examples, they demonstrate the characteristic types of the new kinds of curves and classify them according to their interpretation. With the presentation of a rather large amount of experimental material, the aim of the authors, beyond demonstrating the advantages of the methods, is also to express their disbelief in the justification of calculations of reaction kinetic parameters on the basis of dynamic thermoanalytical curves.
