ABSTRACT:
An economical attrition resistant granular composition for melting ice and inhibiting corrosion of metals and spalling of Portland Cement Concrete and asphalt comprising primarily a water soluble chloride salt, such as sodium chloride, or magnesium chloride; very small amounts of an oxygen scavenger such as sodium nitrite; a surface deactivating corrosion inhibitor such as sodium borate; and an in-situ formed water soluble phosphate salt such as ammonium phosphate amounting to between 1 and 10 percent exhibiting a property of chemically reacting with metal surfaces to form protective coatings of insoluble metal phosphate salts, the soluble phosphate salt serving as an adhesive and a buffering agent to provide hard granules of ice melter with a pH between 5 and 8. A method of preparing the composition is provided.
