ABSTRACT:
There is disclosed a method of forming a urea adduct complex by reacting an aluminum hydrogen phosphate complex which is normally unstable in solution at a pH greater than 2.5 with sufficient urea that no precipitation of alumina occurs on addition of ammonia, and adjusting the pH of the resultant urea adduct complex with ammonia to a value of from 2.5 to 10. The urea adduct complexes of the invention are fire retardants and fire quenching agents and are useful as agricultural adjuvants.
