Abstract:
A forest fire retardant composition includes a retardant compound that includes at least one anhydrous salt and at least one hydrate salt. The anhydrous salt is magnesium chloride, calcium chloride, or both. The hydrate salt is magnesium chloride, calcium chloride, or both. The magnesium chloride hydrate has a formula MgCl(HO), wherein x is at least one of 1, 2, 4, 6, 8, or 12. The calcium chloride hydrate has a formula CaCl)(HO), wherein x is at least one of 1, 2, 4, or 6.
