Description
Tantalum products (Ta) and niobium products (Nb) are rare metals featuring high melting point and high bolting point. They also characterize corrosion resistance, superconductivity and monopolar electrical conductivity.

Application
Tantalum products and niobium products are often applied in electronics, precision ceramic and glass industries. They are also utilized in cemented carbide, aerospace and biomedical engineering industries. In the metallurgical industry, tantalum and niobium are mainly used as additives for producing high strength alloy steel, improving alloy performance and making hard alloy tools.

Classification
1. Tantalum Powder
This tantalum product can be divided into two categories. One is capacitor tantalum, the other is metallurgical tantalum. Tantalum powder capacitors can fulfill its need to reach great capacitance in smaller spaces.
2. Tantalum Ingot
It is widely applied in the chemical, petroleum, medical care, manufacture and commodity-processing industries.
3. Tantalum Bar
This tantalum product is widely used in fabricating chemical process equipment, nuclear reactors, heat exchangers, aircraft and missile parts.
4. Tantalum Tube
Tantalum tube is also normally used as tantalum tubular sputtering target for semiconductor industry. It is generally applied as tantalum cathode with Hollow Cathode Discharge (HCD).
5. Tantalum Sheet
This tantalum product has good machining property in far below room temperature. It also shows excellent corrosion resistance.
6. Tantalum Wire
It features excellent corrosion resistance, high temperature strength, easy to machine and good biocompatibility, mainly used as anode lead in the tantalum capacitors.
7. Tantalum Target
This tantalum product is used for lots of thin film applications such as a diffusion barrier material, memory devices and a gate electrode in MOSFET devices.
8. Tantalum Crucible
Tantalum crucible is used as container for rare-earth metallurgy, corrosion resistant containers in chemical industries and evaporation crucibles.
9. Tantalum Boat
This tantalum product is widely used in vacuum coating industry such as picture tube, mirror, toys, household appliances, mobile phones, electrical appliances shell and various accessories.
10. Niobium Ingot
