Dolomite thermal behaviour: A short review | Physics and
The dolomite sample had a particle size of 400 and 106 μm, treated non-isothermally in air and CO 2 atmospheres. It can be observed that the beginning of the weight loss that marks the beginning of decomposition begins at a lower temperature in air than in a CO 2 atmosphere, indicating that the latter causes thermal stabilization of the carbonate.
