Molybdenum Crucible Production Process

Molybdenum Crucibles can be categorized into sintering molybdenum crucibles and spinning molybdenum crucibles according to different production processes. The Sintering Molybdenum Crucibles are mainly used as high-temperature furnace containers in vacuum, inert, or reducing gases up to 2100 ℃. The Spinning Molybdenum Crucibles are thin-walled crucibles made from a single molybdenum plate by spinning. It is characterized by large size, thin wall thickness, and good resistance to high-temperature creep. The specific sintering processes are as follows:

Raw Material: Select high-purity molybdenum powder.

Powder Metallurgy: Mix with binder and compact into a green billet.

Sintering: High-temperature sintering to remove the binder and increase density.

Heat Treatment: Anneal to relieve stress and enhance properties.

Surface Treatment: Clean and polish the surface.

Cutting & Customization: Cut or customize according to requirements.

Forging Process

Material Preparation

The process starts with the preparation of tantalum billet by our advanced reduction techniques, which is crucial to forge a tantalum crucible.

Heat Treatment - Annealing

Our heat treatment annealing process is tailored to each product. It precisely adjusts the metal's mechanical properties, making shaping easier and enhancing performance.

Forging

Using state-of-the-art forging techniques, we forge the heated tantalum billets into the desired crucible shape. The forging process imparts directional strength to the molybdenum, improving its mechanical properties.

Final Annealing

After forming the tantalum into a crucible, it undergoes a final heat treatment. This step is essential for relieving internal stresses, ensuring the crucible reaches its peak performance.

Finishing Processing

The crucible undergoes finishing processes like smoothing and polishing to refine its surface and ensure it meets the required specifications.

Final Product Inspection

Inspect the final Tantalum crucible, including dimensional measurements, surface inspection, chemical composition analysis, etc. This ensures that the final product meets specifications.

Packaging of Tantalum Crucible

Standard Packing

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

FAQ

Q: Why is Tantalum used to make Crucibles?

A: Tantalum is known for its exceptional resistance to corrosion, particularly in strong acids, alkalis, and high-temperature environments. It also has a high melting point of 3,020°C, making it an ideal material for crucibles that need to withstand extreme heat and chemical exposure without deteriorating.

Q: How does a Tantalum Crucible perform in high temperatures?

A: Tantalum Crucibles can withstand extremely high temperatures, making them ideal for use in high-temperature applications such as metal melting, smelting, and material processing. They maintain their integrity at temperatures far exceeding the capabilities of most other crucible materials.

Q: Is a Tantalum Crucible chemically resistant?

A: Yes, Tantalum Crucibles are highly resistant to chemical corrosion, even in aggressive environments. They can handle corrosive substances such as acids (including sulfuric and hydrochloric acids) and alkalis, making them suitable for chemical processing, laboratory experiments, and high-precision manufacturing.
