Tantalum Bracket For Vacuum Furnace

Tantalum is a kind of element with high melting point and excellent drawing performance.  In addition to superior manufacturing capability, it has a low temperature from ductility to brittleness.  Tantalum is most commonly used in electrolytic capacitors.  Another use is for chemical process equipment such as heat exchangers and condensers.  The aerospace and nuclear industries have found various applications for the metal.  Because of its good corrosion resistance and resistance to body fluids, it can be used in repair and surgical equipment.

Tantalum is often found in hot spots of industrial vacuum furnaces.  Because of its unique properties, the metal can survive high temperatures where most other materials would fail instantaneously.  Tantalum's high melting temperature allows it to survive longer in these extreme temperatures.  However, the longer tantalum is exposed to high temperatures, the more likely grain growth and eventual failure will occur.
