The Thermal Decomposition of TlFeO2 to TlFe5O8 and α-Fe2O3The thermal decomposition of TlFeO2 above 800°C under Argon leads to α-Fe2O3. During this process a new phase, TlFe5O8, was observed. The stoichiometry of this new compound was determined by DTA-TG measurements. The Guinier-photograph showed that TlFe5O8 crystallizes hexagonal-rhombohedral with a = 5.928 Å, c = 35.93 Å, c/a = 6.06 and Z = 6 formula units (molar volume 109.8 cm3) in the elementary cell.

Die thermische Zersetzung von TlFeO2 unter Argon führt oberhalb 800°C zu α-Fe2O3, wobei die Phase TlFe5O8 durchlaufen wird. Die Stöchiometrie dieser neuen Verbindung wurde aus DTA-TG-Messungen ermittelt. Nach Guinier-Aufnahmen kristallisiert TlFe5O8 hexagonalrhomboedrisch mit a = 5,928 Å, c = 35,93 Å, c/a = 6,06 und Z = 6 Formeleinheiten (Molvolumen 109,8 cm3) in der Elementarzelle.
