molybdenum powder is a metal powder used in industrial applications. Its properties make it an excellent conductive metal, a non-corrosive and wear-resistant material. It also has a low electrolyte content, which is important in water-based coatings and paints.
Its use is increasing, particularly in the production of metallurgy. It is used in various kinds of sintering processes, as well as in the manufacture of metal alloys and chemical compounds.
The most important application of molybdenum powder is in the construction industry, where it is used for structural applications and in steel-making. It is also widely used in aerospace and automobile industries.
For these purposes, it is necessary to have a high-density molybdenum powder. In this respect, sintering of a large number of small particles can be a solution. The density of such a product can be up to 95% of the theoretical maximum density (TMD).
However, such a high-density molybdenum particle has several disadvantages: It is not stable in air and oxygen at room temperature, and it is easily oxidized. Its oxidation resistance is poor at 400 degC and is reduced quickly after that.
This is due to the fact that carbon diffuses from a saturated matrix to the center of the molybdenum grains, and it reduces the molybdenum oxides. In addition, the diffusion of carbon increases the grain growth.
For this reason, RF plasma sintering can be an effective method to obtain nano-sized molybdenum powder with a higher oxidation resistance. This process is more effective than conventional methods, since it does not require a reduction stage. In addition, this process produces a molybdenum powder with a relatively lower melting point.
