Solid-state synthesis of ferrates is a sophisticated multi-step process. It is very sensitive to many conditions and can lead to different products; some of them could be unknown. Moreover, the ferrates obtained can undergo structural changes by different mechanisms. Mössbauer spectroscopy allows one to see all iron derivatives and to compare their relative contents. It makes it also possible to identify them determining iron oxidation state and coordination polyhedron as well as magnetic properties for each iron compound. Thus, it is considered to be an essential technique for quality control in solid-state ferrate production.
