Tantalum Crucible

Tantalum Crucibles are primarily used in material processing, melting, and synthesis under extreme conditions. They are available in two main forms: seamless and welded. The seamless tantalum crucible is produced using a seamless process that meets requirements. The welded tantalum crucible is made from flat-rolled material through an automatic or semiautomatic fusion welding process without filler metal.

Tantalum  Crucible Applications

• High-temperature materials processing: Tantalum crucibles are widely used in the processing of materials at high temperatures.
• Metal melting: Tantalum crucibles are essential for melting metals like platinum, gold, and other high-temperature alloys.
• Chemical synthesis: Tantalum crucibles are commonly used in chemical reactors where corrosion resistance is critical, such as in the production of specialty chemicals and pharmaceuticals.
• Semiconductor industry: Tantalum crucibles are used for refining semiconductor materials such as polysilicon and gallium arsenide.

Tantalum and Tantalum Alloy

• R05200, unalloyed tantalum, electron-beam furnace vacuum-arc melt, or both
• R05400, unalloyed tantalum, powder-metallurgy consolidation.
• R05255, tantalum alloy, 90 % tantalum, 10 % tungsten, electron-beam furnace of vacuum-arc melt, or both.
• R05252, tantalum alloy, 97.5 % tantalum, 2.5 % tungsten, electron-beam furnace or vacuum-arc melt, or both.
