Ammonium molybdate tetrahydrate Chemical Properties,Usage,Production
Description
Ammonium molybdate tetrahydrate (also referred to as Ammonium heptamolybdate, chemical formula: (NH4)6Mo7O24)), appearing as a colorless solid. It can be manufactured through dissolving the molybdenum trioxide in excess amount of aqueous ammonia and evaporating the solution at the room temperature. It has many applications, e.g. as an analytic reagent for measuring content of phosphates, silicates, arsenates and lead; for the production of molybdenum metal and ceramics; for the production of dehydrogenation and desulphurization catalysts; for the fixing of metals; for electroplating; supplement in the crop fertilizer; as a negative stain in biological electron microscopy; as an analgesic in medical fields.

Chemical Properties
White, crystalline powder. Soluble in water; insoluble in alcohol. Nonflammable.
Uses
Determination of phosphates, arsenates, and lead.
Uses
Ammonium molybdate tetrahydrate is widely utilized in cryo-negative staining which helps to visualize particles while preserving the sample. It is used as a catalyst to desulfurize thiophene and its derivatives. It serves as an analytical reagent to measure the amount of phosphates, silicates, arsenates and lead in an aqueous solution. It is also used in electroplating, in fertilizers for crops and in the production of molybdenum metal and ceramics. It is used as an analgesic in medical field.
General Description
Ammonium molybdate tetrahydrate (AMT) is a molybdenum salt. Study of its extraction from nickel-molybdenum (Ni–Mo) ore by direct hydrometallurgical method has been reported. Its degradation by combustion to form elemental molybdenum powder using metallic reducers has been investigated.
Hazard
Irritant.
