Products Description
Tantalum crucible has 99.95 purity, is used as a container for rare-earth metallurgy, load plates for anodes of tantalum, and niobium electrolytic capacitors sintered at high-temperatures, corrosion-resistant containers in chemical industries, and evaporation crucibles, and liners.
With our many years of experience in the field of powder metallurgy, produces tantalum crucibles of exceptionally high purity, high-density precise size, and smooth surface, but without cracks, voids, and irregular protrusions. Our products have a longer service life, which will help you to save your cost.
Features
Standard: ASTM B521
Grade: R05200, R05400, R05252 (Ta-2.5W), R05255 (Ta-10W)
Purity: >99.95%
High melting point and thermal stability: Tantalum crucibles can be used during material processing and melting due to withstanding high temperatures as it has a melting point above 3000 °C.
Excellent corrosion resistance: Tantalum protects itself adequately in severely corrosive environments because of its virtue resisting strongly corrosive hydrochloric, sulfuric, and nitric acids.
Good thermal conductivity: In heating and cooling processes, tantalum is useful because it enhances their conduction.
Workability and formability: Tantalum can be worked through and formed because of its ductility despite being a strong metal.
Low vapor pressure: For high temperature applications where high material purity is needed, tantalum is useful because it has low vapor pressure and thus low material loss due to evaporation.
Applications
Metal Melting: Tantalum crucibles are common for melting metals and alloys with high melting points like platinum, gold, and other high-temperature alloys. They serve as ideal containers due to their high melting point and corrosion resistance.
Semiconductor Industry: During the refining of semiconductor materials like polycrystalline silicon and gallium arsenide , tantalum crucibles have been used because they provide a stable high-temperature environment which aids in maintaining the material's purity and quality.
Chemical Synthesis: In chemical processes, especially those involving specialty chemicals and pharmaceuticals that use corrosion-resistant containers, tantalum crucibles are reliable reaction vessels for smooth processing that require further chemical actions.
Laboratory Research: Tantalum crucibles are used in laboratories for high-temperature experiments as well as crystal growth. Their stability improves the outcomes of experimental results and purity.
Ceramic & Glass Manufacturing: Tantalum crucibles enable efficient production of ceramic and glass due to their resistance to extreme corrosion during ceramic sintering and glass melting.
