Dolomite — Thermal Decomposition
The mass loss steps during the thermal Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. 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.
