Molybdenum Powder

Molybdenum is a silvery white metal, very hard transition metal, but is softer and more ductile than tungsten.

Molybdenum is a silvery white metal, very hard transition metal, but is softer and more ductile than tungsten produced by reduction on Molybdenum oxide.

Molybdenum powder is used in powder metallurgy for the following applications:

  • Processing fabricated metal products: Such as wire, sheets, sintered alloys, and electronic components
  • Allying: For example, brake pads, ceramic metallization, diamond tooling, infiltration, and metal injection molding
  • Production of alloys: Such as stainless steel and superalloys
  • Specialty steel: Molybdenum has a high melting point and high conductivity
  • Semiconductors and electronic devices: Molybdenum has a high melting point and high conductivity
  • Melting and casting: Molybdenum powder is pressed and sintered into pellets.
  • Improving paper: Molybdenum powder can improve the brightness, bulk density, opacity, and porosity of paper.
