Abstract
The temperature and enthalpy of fusion of silver were measured in a differential thermal analyzer with gold and aluminum as reference materials. The measurement procedures and the data calibration (or correction) procedures used successfully in our laboratory for differential scanning calorimetry were applied. The experimental fusion temperature, (1233.9±1.0)K, and enthalpy, (108.4±3.3) J·g−1, are compared with the assigned value of temperature for the IPTS-68 scale, 1235.08 K, and with a value for enthalpy, 110.75 J·g−1.
Zusammenfassung
In einem DTA-Gerät wurden unter Einsatz der Referenzsubstanzen Gold und Aluminium die Schmelztemperatur und Schmelzenthalpie von Silber bestimmt. Dabei wurde das in unserem Labor für DSC erfolgreich eingesetzte Meßverfahren und Datenkalibrier- (oder Korrektions-) verfahren verwendet. Die experimentelle Schmelztemperatur (1233.91.0)K und Enthalpie (108.43.3) J·g−1 wurden mit dem zugeordneten Temperaturwert für die IPTS-68 Skala, 1235.08 K und mit dem Wert für die Enthalpie 110.75 J·g−1 verglichen.
