Molybdenu crucible is applying in single crystal growing melting environment,such as LED sapphire and AlN growing.
Crystal growth is a major stage of a crystallization process, which typically follows an initial stage of either homogeneous or heterogeneous (surface catalyzed) nucleation.
Crystal growth is a significant step for the semiconductor industry as well as for optical applications and solar industries. Sapphire single crystals are used for high power laser optics, high pressure components and substrates for LEDs. Aluminum Nitride(AlN) single crystals are the principal components for fabricating UV-LEDs and laser diodes (LDs).
We can produce many varieties of tungsten and molybdenum crucibles for single crystal growing process as a high temperature durability container in this application with its best properties.

1. Physical and chemical properties
(1) Density: 9.5~10.2g /cm3(2) Surface roughness: < 3.2
(3) Purity:Mo 99.97%(min.)
(4) Application temperature environment:1200~1800
2. Applications
Molybdenum has a higher melting point 2620, lower than tungsten. Similar with tungsten crucible, the Mo crucible is also widely applied in high temperature environment such as LED sapphire and single crystal growing , rare earth melting, sintering boats. The working temperature of Mo crucible is above 1200. For single crystal growing furnace, high-purity, high-density, no crack Mo crucible with other features of exact measurement and smooth surface has decisive influence on the success of crystal growth, quality control of pulling crystal, discharging and service life during single crystal growing process.
3. Advantage of our Molybdenum crucibles:- specially precise forming technology for crucible body - uniform grain with densified microstructure ensures longer life time - ready for use parts with precise machining tolerance.
