Improved methods for the controlled generation of ammonia from an ammoniated metal salt at substantially ambient temperature by applying microwave energy to the salt. The ammoniated salts have the formula MAn?(NH3), wherein M is at least one metal selected from the group consisting of alkali metals, alkaline earth metals, scandium, ytterbium, the lanthanides, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese, technetium, rhenium, iron, ruthenium, osmium, cobalt, rhodium, iridium, nickel, palladium, platinum, copper, silver, gold, zinc, cadmium, mercury, tin, and aluminum; A is at least one ion selected from the group consisting Cl-, Br-, F-, I-, ClO3-, ClO4-, BF4-, AlCl4-, PF6-, SbCl6-, and SbF6-; and SbF6- n is from 1 to 6; and X is from 1 to 8. The methods are useful in, inter alia, absorption type refrigeration systems where ammonia is used as a refrigerant and the salt is used as a sorbent bed.
