TLDR
The mechanism of the single-step dehydration of ZnC 2 O 4 · 2H 2 O has been established from TG, DTA and DSC studies as discussed by the authors, where the rate-controlling process for the reaction is random nucleation with the formation of one nucleus on each particle.About:

Journal ArticleDOI
The thermal decomposition of oxalates. A review
TL;DR: In this article, the thermal decomposition and stability of oxalates are reviewed from the viewpoint of their characteristic features rather than by a complete coverage of the existing literature, which is found to often be repetitive in nature.
Journal ArticleDOI
New equations for kinetic analysis of non-isothermal reactions
TL;DR: In this article, a linear dependence of the logarithm of the Arrhenius temperature integral ln p(x) on x (= E R T ), its slope on x−1 and its intercept on In x, respectively, has been derived for non-isothermal experiments.
Journal ArticleDOI
Studies on the mechanism of thermal dehydration of cobalt oxalate dihydrate
TL;DR: In this paper, a phase boundary reaction mechanism is proposed for the dehydration step of cobalt oxalate dihydrate, which combines mechanistic and non-mechanistic equations to compute kinetic parameters.

Nonisothermal dehydration kinetics of sodium-light lanthanoid double sulfate monohydrates
Önder Kolcu,B. Zümreoğlu-Karan +1 more
TL;DR: Dehydration kinetics of double sulfate monohydrates have been evaluated by applying two methods of different categories for the analysis of dynamic TG data as discussed by the authors, and the possible mechanism was found to be diffusion controlled.

Quantitative correlations of activation parameters and procedural factors—dependence on reaction type
TL;DR: The dependence of the correlation of kinetic parameters (energy of activation and preexponential factor) and procedural factors (sample mass and heating rate) on the type of reaction in non-isothermal thermogravimetry is established in this article.

Study of the kinetics of the mechanism of solid-state reactions at increasing temperatures
Jaroslav Šesták,Gunnar Berggren +1 more
TL;DR: In this paper, the importance of the correct selection for the assessment of the progress of the reaction and the acquisition of representative experimental data, as well as the effect of non-isothermal conditions and possible change of the equilibrium on the kinetic equation are stressed.
