Tantalum Crucible
Tantalum Crucible
Tantalum crucibles are containers made of tantalum, a rare and hard metal with a high melting point of 3,017 °C (5,463 °F). Tantalum crucibles are widely used in high-temperature applications such as chemical processing, semiconductor manufacturing, and metallurgy. They are preferred over other materials due to their excellent resistance to corrosion, high thermal conductivity, and low coefficient of thermal expansion. Tantalum crucibles are available in various sizes and shapes, and they can be customized to meet specific requirements. They are typically made by vacuum arc melting, powder metallurgy, or hot isostatic pressing techniques. Tantalum crucibles are an essential component in various industries that require high-temperature processing and storage of chemicals and materials.
