Abstract
A non-toxic chemical composition inhibits corrosion in metal substrates. The composition contains a Phosphorus compound, comprising an acid and a metal selected from the group consisting of an alkali, alkaline earth, or transition metal. The composition also contains a Boron compound comprising an acid and a metal selected from the group consisting of an alkali, alkaline earth, or transition metal. A process of making the chemical composition comprises the steps of filling a mixer with 30-60% by weight of hot water and adding 10-20% by weight of barium carbonate or strontium carbonate, 10-20% by weight of phosphoric acid (75%), 5-15% by weight of lime, and 10-20% by weight of Boric acid; mixing the said contents for 10-15 minutes to create a wet slurry; pouring said wet slurry into an attrition mill for 15-60 minutes; drying said wet slurry and milling said wet slurry to an average particle size of 1.0-2.0 microns to form a dry pigment; pushing said dry pigment through a 325 mesh sieve.
