Thermal decomposition of calcite: Mechanisms of formation and textural evolution of CaO nanocrystals
Carlos Rodriguez-Navarro,Encarnación Ruiz-Agudo,A. Luque,Alejandro B. Rodríguez-Navarro,Miguel Ortega-Huertas +4 more
TL;DR: In this paper, a model for the thermal decomposition of calcite was proposed to explain how decarbonation occurs at the atomic scale via a topotactic mechanism, which is independent of the experimental conditions.

TL;DR: In this article, it was shown that even if PSD exists, a reliable activation energy E can be obtained from such overall kinetic curves by the empirical isothermal analysis without accounting for the PSD.

Calcium carbonate decomposition
TL;DR: In this paper, the results are reported and critically evaluated in the light of the data obtained, and the kinetic parameters as reported by Hyatt et al. (J Am Ceram Soc 41:70-74, 1) are reevaluated.

The effects of sample size and heating rate on the kinetics of the thermal decomposition of CaCO3
P.K. Gallagher,D.W. Johnson +1 more
TL;DR: In this paper, isothermal and dynamic methods were used to study the rate of weight loss of CaCO3 and a pronounced dependence of the activation enthalpy, pre-exponential term, and rate constant upon sample weight and heating rate was observed.

Study of the thermal decomposition reaction mechanism of alkaline-earth carbonates under high vacuum by both thermogravimetric analysis and constant decomposition rate thermal analysis techniques
TL;DR: In this article, both thermogravimetric analysis (TG) and constant rate thermal analysis (CRTA) were applied to the study of the mechanism of thermal decomposition of alkaline-earth carbonates proper experimental conditions were used in order to avoid heat and mass transfer phenomena.
