Tantalum Material Technology and Application

Tantalum has a series of excellent properties, such as high melting point, low vapor pressure, good cold working performance, high chemical stability, strong corrosion resistance to liquid metals, large dielectric constant of surface oxide film and so on. It has important applications in high-tech fields such as electronics, metallurgy, iron and steel, chemical industry, cemented carbide, atomic energy, superconducting technology, automotive electronics, aerospace, medical health and scientific research. At present, the main application of tantalum is tantalum capacitor.

Application of Tantalum in Electronic Industry

In the electronic industry, tantalum is mainly used as tantalum capacitor, usually in the form of capacitor-grade tantalum powder, tantalum wire and tantalum foil. Tantalum capacitor is one of the indispensable electronic components for radar, aerospace vehicle and missile, and is widely used in civil applications, such as mobile communications, electronic equipment, instruments and so on.

Tantalum powder has large specific surface area and dielectric film dielectric constant, so it has large capacitance and can be made into small capacitors. Tantalum electrolytic capacitors have the advantages of small size, light weight, good reliability, wide operating temperature range, seismic resistance and long service life.


Tantalum electrolytic capacitors can be divided into solid electrolyte capacitors and liquid electrolyte capacitors according to their point interpretation. Tantalum electrolytic capacitors can be divided into two types according to their anode forms: tantalum foil anode and tantalum powder sintered anode. Ta wire is used as the anode lead of these two capacitors.

The development of electronic industry requires more and more stringent miniaturization and high reliability of tantalum capacitors. In terms of miniaturization of point tantalum capacitors and chip Xinghua, we are committed to improving the specific capacity of tantalum powder. At present, the commercialized specific capacity of tantalum powder has reached more than 150 000 mu F. V / g in the world and 30 000 mu F. V / g in the laboratory.

Tantalum is used as the material of electronic tubes. Because of its high melting point, low true pressure, good processing performance, low linear expansion coefficient and good suction, tantalum is a good material for transmitting tube and high power electronic tube parts.
