Sintered Tungsten Crucible

Description
Sintered tungsten crucible, thanks to its resistance to certain molten metals and metal oxides, is widely used in many fields. They can be applied in technologies for growing monocrystals from molten corundum. Also they are used for thermal vaporization and deposition of various substances in electronics.

Features
1. The overall density of tungsten crucibles 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 can be more than 200mm.
4. The surface roughness of tooled crucibles does not exceed Rz 6.3.
5. The use temperature of tungsten crucibles should be below 2450ºC in vacuum or deoxidize atmosphere.
6. The shapes and dimensions of sintered tungsten crucible 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 tungsten 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 annealment process should be supported with a vacuum at Р < 10-4 mmhg;
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.
