21% Ultra Phos
Ultra-Phos is manufactured by reacting feed grade defluorinated phosphoric acid with high grade calcium carbonate under controlled conditions. A unique process produces a product with a very high percentage of monocalcium phosphate mixed with a small amount of dicalcium phosphate. The predominant compound is monocalcium phosphate monohydrate. The result is a product which contains a higher percentage of monocalcium phosphate than most commercial feed grade calcium phosphates.
