Description of Tungsten Crucible: Purity: W99.95% Density: 18.2g/cc Application temperature environment：2300C Application of Tungsten Crucible: Tungsten crucible is widely used to the sapphire growth furnaces, quartz glass melting furnace, crystal furnace, induction furnace, sintering metal mold o
Sapphire boules are grown from the melt in molybdenum crucibles with growth initiating off a melted-back seed at the bottom center of the crucible and progressing three-dimensionally toward the top and sides of the crucible. This: • promotes removal of volatile species from the melt surface,
The present invention relates to a sapphire single crystal growing apparatus and a sapphire single crystal growth using the same room using the crucible support and the furnace (furnace); Located inside the furnace, a sapphire material is melted, at least one crucible to grow a single crystal from the seed crystal; It is disposed outside the furnace heating element for heating the crucible
Pool of furnace and cutting equipment applied for crucible production will be updated. During exploitation process in leucosapphire growing plant defects are formed on the surface of inner and outer crucible faces: local molybdenum deposition at outer face the source of which is molybdenum equipment;
Optical mirrors have a smooth, highly-polished, plane or curved surface for reflecting light. Usually, the reflecting surface is a thin coating of silver, or aluminum on glass. Product specifications for optical mirrors include diameter, radius

Sapphire shaped crystals were grown from the melt in the  orientation by the EFG and GES (Growth from an Element of Shape) methods. These experiments were performed in a 8 KHz induction furnace, with the heated graphite susceptor radiating on the molybdenum crucible, dies and thermal shields.
Tungsten crucible is widely used in technologies for growing monocrystals from molten corundum, it is also used in electronics and technologies for thermal vaporization - deposition of various substances. It is an important part in high temperature furnace cause its high melting point.
AEM can provide forged molybdenum crucible and sintered molybdenum crucible. With our many years of experience in the field of powder metallurgy, we produce crucibles of a particularly high purity, high density precise size and smooth surface, but without cracks, voids and irregular protrusions.

The high purity of molybdenum metal (99.97% is typical) assures contaminant-free sapphire with the best properties. Growing the sapphire substrate Most LED substrates are grown using one of two methods: the Kyropoulos method and the Heat Exchanger method. In the Kyropoulos method, a molybdenum crucible is filled with pure alumina (Al2O3) powder
Spinning forming Technology of Molybdenum Crucible. Mosten; 26 Aug; Molybdenum is a kind of rare metal, which is an important strategic material that canundefinedt be regenerated. Molybdenum is an important base material for the modernization of the country and the construction of modern national defense.
