Abstract

Differential thermal analysis technique has been applied to determine the heat of reduction of iron oxide by aluminium. It has been observed that the DTA curve can be used for quantitative determination of heats of reactions at high temperature ranges where differential scanning calorimetry is not applicable. The experimental results obtained agree closely with the theoretical value of the heat of reaction.

Zusammenfassung

Unter Anwendung von DTA wurde die Bestimmung der Reaktionswärme der Reduktion von Eisenoxid mit Aluminium durchgeführt. Es konnte festgestellt werden, daß DTA zur quantitativen Bestimmung von Reaktionswärmen bei hohen Temperaturen geeignet ist, bei denen DSC nicht mehr angewendet werden kann. Die ermittelten experimentellen Ergebnisse stimmen gut mit dem theoretischen Wert für die Reaktionswärme überein.
