• 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.
• Uses: Determination of phosphates, arsenates, and lead. 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.
