Abstract: FERROUS METAL IS CORROSION-PROOFED WITH A SOLUTION OBTAINED BY TREATING CHROMITE ORE OR OTHER OXIDE WITH GALLIC ACID. OTHER CHELATING AGENTS MAY REPLACE THE GALLIC ACID. THE SOLUTIONS CAN ALSO BE USED FOR THE DEPOSITION OF OXIDES ON INEXPENSIVE MINERAL MATERIAL TO FORM ATTRITION-RESISTANT SUPPORTED CATALYSTS.

Abstract: Treatment of metals, and other surfaces, with dilute colloidal slightly acidic dispersion of silica and tannin. The treating composition is removed from the metal surface before forming any deposit of silica visible to the naked eye. The metals become resistant to chemical attack.
