Molybdenum Powder

Molybdenum is a silver-grey metal with a melting point of 2623 ℃ and a density of 10.2 g/cm³. It is one of the commercially available metals with the lowest coefficient of thermal expansion. Molybdenum Powder is commonly produced by reducing ammonium paramolybdate or calcined MoO3 with hydrogen. The oxygen content can be reduced to lower levels through specific reduction conditions. HM can supply high-quality irregular and spherical molybdenum powder with particle sizes from coarse to ultra-fine.

Molybdenum Powder Production Method

Molybdenum Powder can be produced using various methods, with hydrogen reduction being the most commonly employed industrial process. This method allows precise control over the powder’s morphology, particle size, and purity.

Hydrogen Reduction: Reduction of molybdenum trioxide with hydrogen to produce molybdenum powder.
Thermal Decomposition: Heating molybdenum compounds such as ammonium molybdate to form molybdenum oxide followed by hydrogen reduction.
Electrolytic Production: Molybdenum powder precipitates are produced by aqueous electrolytic precipitation from an acidic molybdate solution.
Calcium Thermal Reduction: Reduction of molybdenum trioxide using calcium.

Molybdenum Powder Applications

Powder Metallurgy: Molybdenum powder is an important raw material for producing molybdenum alloys and molybdenum products, and is widely used to manufacture high-strength, high-temperature alloys and corrosion-resistant alloys.
Electronic Industry: Molybdenum powder is also used to manufacture electronic components such as electrodes, semiconductor devices, and electrode wires for EDM machines.
Chemical Industry: Molybdenum powder is used as a catalyst and corrosion-resistant material in the chemical and petroleum industries.
Aerospace: Molybdenum powder is used to manufacture high-temperature components such as gas turbine blades and guide vanes for jet engines.
Glass and Ceramics Industry: Molybdenum powder is also used to manufacture heaters for high-temperature furnaces and electrodes for glass-melting furnaces.

Molybdenum Powder Packaging

The Molybdenum Powder is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
