Tantalum has features like low vapor pressure,high chemical stability, good cold workability, strong resistance to liquid metal corrosion, large dielectric constant of surface oxide film etc. Which melting point up to 2980 ℃, second only to tungsten and rhenium. In addition, tantalum products are widely used in industry and daily life.

1. Tantalum is mainly capacitors for electronic equipment. Capacitors are electrical components that store electrostatic energy in an electric field. Tantalum capacitors are widely used in communications ,automobiles, household ,computers and office appliances, instrumentation, defense, aerospace and military industries , other industrial and scientific sectors.

2. Non capacitor uses in electronics have created a demand for tantalum sputtering targets and tantalum chemicals for audio and video components.
3. In the chemical industry, tantalum can be used to replace stainless steel in the equipment for making various inorganic acids, and the life of the equipment can be increased by dozens of times compared with the use of stainless steel.
4. In the aerospace and military fields, tantalum tungsten, tantalum tungsten hafnium, tantalum hafnium alloy are used as heat-resistant high-strength materials for rockets, missiles, and jet engines, as well as parts for control and regulation equipment.
5. In the field of electronics, tantalum is used to make electron emission tubes and high-power electron tantalum tube and tantalum parts.
6. In the field of healthcare, tantalum and its alloys can be used as a material for orthopedics and surgery. For example, tantalum strips can be used to replace bones in the human body, and muscles can also grow on the tantalum strips.
7. In the field of metallurgy, tantalum and its alloys can be used as heat shields, heaters, and heat sinks in high-temperature vacuum furnaces(tantalum crucible) because it has a high melting point and is easy to process and form.
8. In the atomic energy industry, tantalum borides, silicides, and nitrides, and their alloys can be used as heat release elements and liquid metal sheath materials.
9. In addition, tantalum wire is used as anode lead by capacitor manufacturers. Tantalum is also used for sintering tray components and shielding components of anode sintering furnace.
