Is the science of thermal analysis kinetics based on solid foundations?: A literature appraisal
TL;DR: A critical appraisal of the recent literature concerned with the kinetics and the mechanisms of thermal reactions, particularly research using the methods of thermal analysis (TA) is made in this article, concluding that many features of the theories and the practices in customary use are inadequate and/or unsatisfactory.

Controlled transformation rate thermal analysis: the hidden face of thermal analysis
TL;DR: Controlled transformation rate thermal analysis (CTRTA) as mentioned in this paper is a general thermoanalytical method where, instead of controlling the temperature (as in conventional thermal analysis), one controls some other physical or chemical property, which is made to follow a pre-determined program by appropriate heating of the sample.

Use of the Langmuir method for kinetic studies of decomposition reactions: calcite (CaCO3)
Dario Beruto,Alan W. Searcy +1 more
TL;DR: In this article, the Hertz-Knudsen-Langmuir equation was used to measure the isothermal weight loss in vacuum from cleavage (10textdecoration:overline11) planes of calcite (CaCO3) single crystals.

Kinetics of the thermal decomposition of CaCo3 in Co2 and some observations on the kinetic compensation effect
P.K. Gallagher,D.W. Johnson +1 more
TL;DR: In this article, the authors investigated the kinetics of the thermal decomposition of CaCO 3 in CO 2 using both dynamic and isothermal techniques and concluded that thermal transport rather than mass transport or chemical processes is rate determining.

Thermal decomposition reactions of solids controlled by diffusion and phase-boundary processes: possible misinterpretation of the mechanism from thermogravimetric data
José M. Criado,Julián Morales +1 more
TL;DR: In this paper, a comparative study of phase-boundary and diffusion-controlled reactions has been carried out using thermogravimetric data, and the results reported support the hypothesis that a single TG diagram does not allow the determination of whether a solid decomposition reaction is controlled by a diffusion mechanism or governed by the movement of an interface coming from a nucleation process.
