7. Application:
It has very good properties of corrosion resistance.It also has good electrical conducivity and easy be machined in the room temperature.The most application of tantalum is electrical industry,such as capacitors and etc.
Feature:
Tantalum Rings is dark (blue-gray),dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The metal is
renowned for its resistance to corrosion by acids; in fact, at temperatures below 150 °C tantalum is almost
completely immune to attack by the normally aggressive aqua regia. It can be dissolved with hydrofluoric acid
or acidic solutions containing the fluoride ion and sulfur trioxide, as well as with a solution of potassium
hydroxide. Tantalum's high melting point of 3017 °C (boiling point 5458 °C) is exceeded among the elements
only by tungsten, rhenium and osmium for metals, and carbon.
