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.[1] Its degradation by combustion to form elemental molybdenum powder using metallic reducers has been investigated.[2]

Application

Ammonium molybdate tetrahydrate may be used in the following processes:

As a precursor in the generation of calcium molybdate (CaMoO₄) spherulites.[3]
Synthesis of porous carbon-supported molybdenum dioxide (MoO₂).[4]
Preparation of Iodine-iodide-molybdate solution to determine glucose level by glucose oxidase method.[5]
Preparation of polymer bulk heterojunction solar cells.[6]
As a precursor in the synthesis of Mo-N-codoped TiO₂(titanium dioxide).[7]
Synthesis of MoBi₂S₅(molybdenum bismuth sulphide) thin films.[8]

Applied in the ultrasonic synthesis of phase-pure praseodymium molybdate, Pr₂Mo₃O₁₂.[9]
Reagent used for oxidation of sulfides to sulfonyls.[10]
