Abstract

By means of TG, the thermal decomposition of the powdered CaCO3 was tested with its various dispersities, range of size, and the different content of CO2 in flowing nitrogen. Formulae for calculating the rate and time of decomposition were obtained.

Zusammenfassung

Mittels TG wurde die thermische Zersetzung von pulverförmigem CaCO3 in Abhängigkeit vom Dispersionsgrad, Größenbereich und vom CO2-Gehalt der Stickstoffatmosphäre untersucht. Dabei wurden Formeln für die Berechnung der Zersetzungsgeschwindigkeit und-dauer erstellt.
