Crystal structure and Mössbauer study of FeAl2O4

In this work the synthesis of hercynite from Fe and Al powders was carried out by arc-melting method under the protective argon atmosphere. The obtained material was characterized with the use of powder X-ray diffractometry (XRD) and Mössbauer spectroscopy (MS). A Mössbauer effect in hercynite obtai...

Summary:In this work the synthesis of hercynite from Fe and Al powders was carried out by arc-melting method under the protective argon atmosphere. The obtained material was characterized with the use of powder X-ray diffractometry (XRD) and Mössbauer spectroscopy (MS). A Mössbauer effect in hercynite obtained by the arc-melting method indicated the cations distribution in the spinel structure among the tetrahedral and octahedral interstices. The presence of Fe ions was detected in both tetrahedral and octahedral sites while Fe ions occupied only the octahedral interstices. The approximate formula of the obtained iron-aluminate spinel was as follows (Fe Al ) (Fe Fe Al
