Molybdenum Crucibles in Vietnam

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
