The metamorphic interaction between carbonate and silica-rich fluid is common in geological environments. The formation of talc from dolomite and silica-rich fluid occurs at low temperatures in the metamorphism of the CaO–MgO–SiO2–CO2–H2O system and plays important roles in the formation of economically viable talc deposits, the …

· Even though CaMg(CO 3) 2 required a minimum temperature of 300 °C for formation in contrast to MgCO 3, it generally displayed a faster nucleation rate, which was profitable mainly when applying a low CaCO 3 to MgO molar ratio. However, the CaMg(CO 3) 2 decomposition demanded higher temperatures than MgCO 3, which were associated with more ...

· Gallai et al. studied the mechanisms of growth of MgO and CaCO 3 during the dolomite partial decomposition under CO 2 pressure of 0.02–0.5 atm. They reported that the decomposition rate is limited by the diffusion of Mg from CaCO 3 /MgO interface to MgO/CO 2 interface. Fine particles of MgO are formed at the surface of the initial dolomite ...
This supports the reaction CaMg(CO,), + CaCO, + MgO + CO, (3) as being responsible for the first stage of dolomite decomposition under a CO, atmosphere. Furthermore, the growth of the peak at 29.2" 28 rather than a gradual shifting of the dolomite peak from 30.6" 20 suggests the formation of discrete CaCO, rather than a gradual change in the ...

· In this work, the MgO-CO 2 working pair has been adapted for thermochemical energy storage (TCES) at medium temperatures by the MgO modification with inorganic salts to promote the TCES dynamics.
· The dolomite was utilized as a source of calcium oxide (CaO) and magnesium oxide (MgO). The main characteristic of this rock is the high content of CaMg(CO 3) 2 which was transformed into CaO·MgO mixed oxide by calcination. The activation method to improve the activity, basicity and stability of catalyst has been investigated.
