Abstract: | The reduction of BaSO4 by carbon was investigated by means of isothermal thermogravimetric measurements. In combination with a high-temperature thermobalance, solid electrolyte cells were used (i) to purify the N2 flow gas, and (ii) to measure the partial pressure of oxygen (CO CO2 ratio, respectively) in the outlet gases.Mass loss curves and
in the outlet gases were recorded at 743–955 °C. The activation energy of the process was calculated from the isothermal TG curves. X-ray diffraction and SEM showed that the solid product in the whole temperature interval comprised only cubic BaS.
Zusammenfassung Die Reduktion von BaSO4 mit Kohlenstoff wurde durch isotherme thermogravimetrische Messungen verfolgt. Mit einer Hochtemperatur-Thermowaage wurden Festelektrolyten kombiniert (1)zur Reinigung des Spülgases N2 von Sauerstoff, (2) zur Messung des O2-Partialdruckes (bzw. des Verhältnisses CO CO2) im entweichenden Gas. Die Gewichtsverlust- und Sauerstoffpartialdruck-Kurven bei 743–955 °C wurden aufgezeichnet. Aus den TG-Kurven wurde die Aktivierungsenergie des Prozesses berechnet. Im gesamten untersuchten Temperaturbereich entstand als festes Reaktionsprodukt nach Röntgenbeugungs- und SEM-Untersuchungen nur kubisches B2S.
