Ammonium molybdate is an inorganic compound with the formula (NH4)6Mo7O24, known for its extensive application in various fields.
It falls under several regulations and is also recognized as a hazardous substance and a toxic air pollutant under various laws.
Ammonium molybdate serves as a precursor for molybdenum metal production and as a catalyst in Trost oxidation. It finds uses in metal surface treatments, as a flame retardant, smoke reducer, and additive in ceramics and sintered metals. Analytically, it determines silicates, phosphates, arsenates, and lead in solutions. Additionally, it is utilized in recreational drug detection and biological electron microscopy, aiding in the production of dehydrogenated desulfurized crystals, metallic molybdenum, and ceramics.
This compound appears as a white or almost white crystalline or powdered substance, odorless and soluble in water but insoluble in ethanol and acetone. Generally non-toxic, Ammonium molybdate has been associated with few accidents.
Commonly found as a tetrahydrate (NH4)6Mo7O24•4H2O, dihydrate forms are also known. It features a heptamolybdate ion (Mo7O246-), referred to as para-molybdate. All molybdenum centers in its structure are octahedral, with oxide ligands exhibiting terminal, doubly bridged, and triple-bridged configurations.
Molybdenum(VI) oxide, dissolved in an aqueous ammonia solution and evaporated at room temperature, forms ammonium molybdate. This process yields tetrahydrate crystals through ammonia evaporation, reacting with acid to produce molybdic acid and ammonium salts.
Potassium molybdate, structurally similar to ammonium molybdate, is also obtained as a tetrahydrate, highlighting the versatile nature of molybdate compounds.
