Performance of Tantalum Capillary under High Temperature Conditions

Tantalum capillary exhibits excellent performance under high temperature conditions, which is mainly reflected in the following aspects:
• Extremely high melting point and thermal stability
Tantalum has a melting point of about 2996°C (about 3270K), which is much higher than many commonly used metal materials. This enables tantalum capillary to work stably for a long time in extremely high temperature environments and is not easy to melt or deform.
• Excellent high temperature corrosion resistance
Tantalum can form a dense oxide film at high temperature, has good anti-oxidation and corrosion resistance, can resist the erosion of a variety of high temperature corrosive media, and is suitable for high temperature chemical reactions and liquid metal environments.
• Good mechanical property retention
Tantalum capillary can still maintain high strength and toughness under high temperature conditions, avoid embrittlement or mechanical property degradation caused by high temperature, and ensure the stability and safety of the structure.
• Reliability of high-temperature heating applications
Research shows that tantalum capillaries can be used in high-temperature heating devices, such as metal capillary atomic sources, whose operating temperature can reach above 2300K, and the heating power is low and the temperature distribution is uniform, which overcomes the "cold spot" effect during the heating process and ensures the stability and efficiency of heating.
• Advantages of heat conduction and heat capacity
Tantalum capillaries have a small heat capacity and can quickly reach the thermal equilibrium temperature, which is suitable for high-temperature conditions that require rapid heating and precise temperature control.
In summary, tantalum capillaries are an ideal material choice for high-temperature environments due to their extremely high melting point, excellent high-temperature corrosion resistance, good mechanical properties and thermal stability. They are widely used in high-temperature chemical reactions, liquid metal transportation, high-temperature heating equipment and other fields.
