Thermal decomposition of calcite: Mechanisms of formation and textural evolution of CaO nanocrystals

Kinetic study of the thermal decomposition process of calcite particles in air and CO2 atmosphere

“…The value obtained for the apparent activation energy (139000 J/mol) is of the same order as or intermediate among the values proposed by other researchers [14,[44][45][46][47][48][49] that have studied this process (Table 2).…”

“…Bear in mind that the effective diffusivity in porous solids is in direct proportion with their porosity [13,[48][49][50][51][52].…”

Characterization of desert sand as a sensible thermal energy storage medium

“…Furthermore, the comparison of the decomposition patterns and onset temperatures with those available in the literature [8] support the identification of the decomposing compound as calcium carbonate. In this regard, the original mass fraction of calcium carbonate in each sample may be considered as proportional to the relative mass loss [9].…”

Frictional Instabilities and Carbonation of Basalts Triggered by Injection of Pressurized H2O‐ and CO2‐ Rich Fluids

“…Adhesive wear products were also found in experiments performed with H 2 O‐rich fluids, suggesting the achievement of high temperatures despite the presence of water that should buffer the temperature increase (Violay et al, 2014). Furthermore, since thermal decomposition of dolomite and calcite happens at a temperature ranging from 600 to 800°C, this temperature interval can be reasonably regarded as an upper bound of the temperature reached in the slipping zone at the main frictional instability (Rodriguez‐Navarro et al, 2009, 2012). …”
