Fe2As has been studied in-situ by synchrotron PXRD over the range of temperatures 25-850 ◦C and under neutral atmosphere to understand its thermal behaviour, which is potentially important for gold extraction. For the first time, incongruent high temperature reactions of Fe2As are observed as it breaks down and the existence of a previously-undiscovered high-temperature FeAs phase with NiAs-type structure has been determined experimentally. No evidence has been found for existence of the high-temperature phase Fe3As2. Hence, the previously published phase diagram for the Fe-As system has to be modified accordingly.
