Description
- 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]
- Features and Benefits: Meets A.C.S. reagent specificatons.
