Tungsten Crucible

Tungsten crucible
sintered tungsten crucible
sintered tungsten crucible is applied to many fields because its melting metals and metal oxide have certain corrosion resistant properties. It can be applied to fused corundum crystal growth techniques. Sintered tungsten crucible also can be hot evaporation and hot deposition’s container for various material in electrons.
tungsten crucible for vacuum coating
according to different manufacturing ways, the tungsten crucible for vacuum coating mainly are divided into sintering, pressing, rotatable, machining and welding shape, which machining shape is the most common. We suggest tungsten crucible for vacuum coating’s working temperature should be controlled below 2600℃. In the area of optical glass, tungsten crucibles for vacuum coating are mostly used for containers and heating elements of vacuumed coating machines. Also it owns high thermal conductivity and good hardness.
