Description

Sintered tungsten crucible
Sintered with tungsten powder the sintered tungsten crucibles are multi-purpose production in sintering furnace, large crystal growth furnace. Thickness of sintered tungsten crucibles is usually 8-12 mm; diameter is typically 100-550 mm; height is typically 50-700 mm. Such crucible Purity: W ≥ 99.95%; density is usually up 18.2g/cm3, by special needs the density can up 18.8g/cm3 or more.

Features:
1.The overall density of sintered tungsten crucible is fairy high between 18g/cm3 to 18.3g/cm3;
2.Its chemical purity of sintered tungsten crucible can be above 99.95%;
3.The diameter of sintered tungsten crucible can be above 200mm;
4.The surface roughness of tooled crucibles does not exceed Rz 6.3;
5.The use temperature of sintered tungsten crucible should be below 2450ºC in vacuum or deoxidize atmosphere.
6. The shapes and dimensions of crucibles are also made in accordance with customers' requirements.
material  density  size
W >99.95%  18g/cm3—18.3 g/cm3   Diameter: 100-550mm; Height:50-700mm

Stamped tungsten crucible
The tungsten crucibles can be produced of a tungsten plate by stamping, spinning, or welding. It can be used to produce single-use square or round crucible. Thickness typically 0.5 to 3 mm. Such tungsten crucible Purity: W ≥99.95%; density is usually up 19g/cm3

Forged tungsten crucible
The tungsten crucible can be made of tungsten rod by turning , generally they are smaller and with higher density. Usually the wall thickness 3-10 mm; diameter of 80 mm. They are widely used by sintering furnaces for ceramics and other materials
or vacuum evaporation coating machine. Purity: W ≥ 99.95%; density are usually based on different diameters of up to 18.3 to 19g/cm3

Notice:
1.Before use, it is recommended that the consumer anneal (de-gas) crucibles in a vacuum without batch charging;
2.In a furnace, the annulment process should be supported with a vacuum at P< 10-3mmhg;
3.When preparing a sintered tungsten crucible for work
