Molybdenum Crucibles
Inquiry NowProduct Description
General Information
Molybdenum Crucibles are made up of sintered molybdenum powder. Molybdenum is a refractory metal and has a high melting and boiling point (2622 °C and 4639 °C, respectively). Crucibles made up of molybdenum possess extraordinary strength, and are extremely resistant to corrosion and very high temperatures which also makes them good thermal and electrical conductors.
Molybdenum crucibles can be used to conduct tests with many chemical solutions. At room temperatures, they are non-reactive to hydrochloric acid, hydrofluoric acid and alkali solutions, but dissolve in nitric acid, concentrated sulphuric acid and aqua regia. They oxidise at temperatures between 400 °C – 800 °C under oxidising atmosphere and resulting in molybdenum vaporising. Therefore, it is recommended that for high temperatures, around 2000 °C, experiments with Molybdenum Crucibles should be performed in an inert environment.
Molybdenum Crucible’s robustness, good conductivity, non-reactivity with many chemical substances and resistance to corrosion as well as high temperatures allows it to endure repeated rough handling therefore absolutely makes it a suitable vessel for laboratories.
Molybdenum Crucibles come in a variety of shapes (molybdenum boat crucible, molybdenum cylindrical crucible, molybdenum rectangle crucible etc) and sizes of any diameters and wall thickness that suits your requirements.
Molybdenum Crucibles can be manufactured in different ways as shown below: –
- Pressed and sintered Crucibles
- Spin-formed Crucibles
- Milled Crucibles
- Welded Crucibles

Key Features
Molybdenum is a refractory material that can withstand high temperatures, even higher than steel and nickel alloys. Due to its oxidation at low temperatures, it is best to use Molybdenum Crucibles in vacuum. Significant features include –
- High purity
- Low solubility in water
- High dimensional stability
- Low co-efficient of thermal expansion
- Good thermal conductivity
- Good electrical conductivity
- Long functional life
- High melting point (2622 °C)
- High boiling point (4639 °C)
- High red-hardness
- Tensile strength
- Ductility
- High density
