Sodium metaborate and metasilicate coatings protect pure iron in the temperature range 800 to 1,000-degrees-C. Metaborate and metasilicate inhibit oxidation. Protective vonsenite (4FeO x Fe2O3 x B2O3) forms with metaborate, and protective fayalite (2FeO x SiO2) forms with metasilicate. It is proposed that noncoherent blocking layers of these compounds effectively decrease the interface area for iron ion diffusion.
