What Makes Tungsten Crucibles Valuable
Tungsten has an extremely high melting point, good high-temperature strength and low vapor pressure under vacuum. These properties make tungsten crucibles useful for vacuum melting, sapphire crystal growth, rare earth processing and laboratory experiments involving high heat and controlled atmospheres.
Important Ordering Details
A tungsten crucible quotation should include outside diameter, inside diameter, height, wall thickness, bottom thickness and drawing requirements. If the crucible requires a lid, flange, threaded area or machined groove, these details should be included at the beginning of the inquiry.
- Material purity requirement, such as high-purity tungsten
- Manufacturing route, such as pressed-sintered or machined from tungsten blank
- Surface condition, including machined, polished or cleaned
- Working environment, including vacuum, inert gas or reducing atmosphere
Application Notes
Tungsten crucibles perform best when the service environment is compatible with tungsten. At high temperature, oxidation must be avoided. For furnace use, customers should confirm heating rate, maximum temperature, atmosphere and whether molten material may react with tungsten.
