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 ***2 mm; diameter is typically ******0 mm; height is typically *****0 mm. Such crucible Purity: W ≥ *9.*5%; density is usually up *8.2g/cm3, by special needs  the density can up *8.8g/cm3 or more.

Features:

1.The overall density of sintered tungsten crucible is fairy high between *8g/cm3 to *8.3g/cm3;

2.Its chemical purity of sintered tungsten crucible can be above *9.*5%;

3.The diameter of sintered tungsten crucible can be above **0mm;

4.The surface roughness of tooled crucibles does not exceed Rz 6.3;

5.The use temperature of sintered tungsten crucible should be below ***0ºC in vacuum or deoxidize atmosphere.

6. The shapes and dimensions of crucibles are also made in accordance with customers' requirements.

Package and Inspection:

Every tungsten crucible is under strict nondestructive test and density detection. We offer material composition sheet and examination report of the sintered tungsten crucible. We also pack the crucibles in shock and moisture-proof plywood case independently.

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< ***3mmhg;

3.When preparing a sintered tungsten crucible for work, the consumer should not allow a sharp rise or fall in temperature, or abbreviate the recommended time periods for holding temperatures.

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 ≥*9.*5%; density is usually up *9g/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 ***0 mm; diameter of *0 mm. They are widely used by sintering furnaces for ceramics and other materials 

or vacuum evaporation coating machine.  Purity: W ≥ *9.*5%; density are usually based on different diameters of up to *8.3 to *9g/cm3
