CaMg(CO3)2 + 2 SiO2 = CaMgSi2O6 + 2 CO2. Dolomite + 2 Quartz = Diopside + 2 Carbon Dioxide. Normally we would pick the 4 components: CaO, MgO, SiO2, and CO2 based on the simple oxides. However, because Ca and Mg are in a 1:1 ratio in both dolomite and diopside (and not present in quartz or carbon dioxide), we can consider this a ternary system ...

Using CaMg(CO3)2 as hard template, CaMg(CO3)2@Ag2CO3 microspheres were first obtained via a fast cation exchange process. Then, CaMg(CO3)2@Ag2CO3/Ag2S was fabricated by further anion exchange. Finally, trace nitrogen-doped carbon quantum dots (NCQDs) were coupled into CaMg(CO3)2@Ag2CO3/Ag2S and obtained CaMg …

Abstract The structure of dolomite, CaMg(CO3)2, was determined from 298 to 1466 K at a constant pressure of about 3 GPa using in situ synchrotron X-ray diffraction data to investigate the state of disorder. An order parameter s, defined as 2 xCa - 1, varies from s = 1 (where xCa = 1) for a completely ordered dolomite to s = 0 (where xCa = 0.5) for a completely …

FeOOH in sewage sludge biochar was transformed by sorbed CO2 into Fe(OH)2CO3, while the sorbed CO2 in pig manure biochar was precipitated as K2Ca(CO3)2 and CaMg(CO3)2, which resulted in a dominant increase of insoluble inorganic carbon in both biochars.
