Preparation Of Nano Molybdenum Powder

The technology for the production of nanopowders represents the boundary of modern materials science and technology. The production process for Nano-Molybdenum Powder is no exception. To date, the reported methods for producing Nano-Molybdenum Powder primarily employ the Microwave Plasma method, among others.

Production of Nano-Molybdenum Powder

The microwave plasma method utilises the principle of hydroxyl pyrolysis to produce Molybdenum Powder. A newly developed microwave plasma apparatus is employed. It uses electromagnetic high-frequency oscillations to dissociate the reaction gas. This produces a high-temperature microwave plasma. Compared with other plasma methods, a constant temperature field is maintained. The apparatus discharges the generated CO immediately and rapidly condenses the produced Mo in the collection device. Consequently, nanopowders with smaller particle sizes are obtained compared with the hydroxyl pyrolysis method. Similarly, Mo(CO)6 was pyrolysed under an N2 plasma atmosphere to produce nano-molybdenum powder with uniform particle size. In one step, molybdenum powder with an average particle size of less than 50 nm was produced. The individual particles assumed a nearly spherical shape. The powder was found to be stable in air at room temperature. Thus, the nano-molybdenum powder can be widely used.

Furthermore, electrical impulse discharge was employed for the production of nanopowders. Studies indicated that the discharge occurs when the current reaches 10 kA. The pulse lasts approximately 20 µs, and the pulse energy is about 80 J. In argon, oxygen and nitrogen, metal pulse discharge is used to synthesise nanopowders from metals, metal oxides and metal nitrides, for example Nano-Mo Powder. The particle size range of the powder produced by this method is between 20 and 70 nm.

Reportedly, the particle sizes of molybdenum powder produced by the reduction of MoCl5 or MoCl6 with pure hydrogen by Hermann C. Starck are 1–5 nm and 1–50 nm. The total impurity contents are below 500 mg/kg, 1 000 mg/kg and 200 mg/kg.

Furthermore, both the United States and Japan have investigated mechanical alloying. This method produces catalyst powder from a Ni-Mo alloy with a nanocrystalline structure and an average particle size of less than 10 nm. The powder exhibits catalytic activity that improves the catalyst’s performance.
