Dolomite — Thermal Decomposition

The mass loss steps during the thermal decomposition of dolomite [CaMg(CO3)2] overlap when the measurement is performed in a nitrogen atmosphere. By using CO2 as a purge gas, they can be clearly separated. The calculated DTA signal (c-DTA®) additionally yields the information that both effects are endothermal.
