Tantalum Crucible

Tantalum crucible is a high-purity container used to grow crystals and perform high-temperature chemical reactions.

Key Properties

High Melting Point: Tantalum has a melting point of around 3020°C, making it ideal for use in applications requiring high temperatures.
Corrosion Resistance: It’s highly resistant to corrosion, even against strong acids, except for hydrofluoric acid and acidic solutions containing the fluoride ion.
Non-reactive: Tantalum is inert in many chemical systems, allowing for its use in the electronics and chemical industries without altering the substances in contact.
Ductility: Tantalum can be drawn into fine wires or foils, which can be useful in applications requiring tight sealing, like in vacuum systems.
Biocompatibility: Tantalum is non-toxic and biocompatible, making it suitable for medical equipment and implants.

Dimensions

Diameter: 10 – 700mm
Height: 25 – 900mm
Wall Thickness: 3 – 30mm
Volume Capacity: Can vary from a few milliliters for laboratory use to several liters for industrial applications.

Applications

Crystal Growth: They’re often used to grow single crystals, particularly sapphire crystals for lasers and LEDs.
High-temperature Synthesis: In the synthesis of superalloys and in the production of compounds that require high-temperature processing.
Metal Melting: For melting and casting of superalloys and other metals with high melting temperatures.
Laboratory Equipment: Due to its resistance to chemicals and high temperatures, tantalum crucibles are a good choice for laboratory equipment in various research and development fields.
