A chemical compound containing iron in the sixth oxidation state (Fe⁶⁺), used in water treatment and as an oxidizing agent in chemistry.
From 'ferr-' (iron, from Latin 'ferrum') plus '-ate' suffix indicating a salt or compound; formed following standard chemical nomenclature for ionic compounds.
Ferrate is chemistry's hidden gem—it's one of the strongest oxidizing agents known, and it works as both a disinfectant and a water purifier, yet most people have never heard of it because the chemistry is complex and its uses are largely industrial.
