Abstract
Finely divided iron is mechanically mixed in water to add a coating to the iron particles. Present in the water to protect the iron from corrosion loss during such processing is a small amount of sodium carbonate or tri-sodium phosphate or sodium silicate. The inhibitor is adsorbed on the eventual iron particles after the water is driven off.
