Figure 1:
Extent of the decomposition of hydromagnesite under isothermal conditions. The values of the temperature in °C are marked on the curves. Isothermal experiment should be carried out at temperatures below 150°C to avoid the occurrence of the temperature settling problem. However, investigation scanning times for such temperatures are just not practicable.

Figure 2:
Comparison between TG and DTA (expressed as reaction progress , normalized signals) for the decomposition of hydromagnesite under isothermal conditions (250°C).
