Application Areas Of Tantalum

Tantalum has a series of excellent properties such as high melting point, low vapor pressure, good cold working performance, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of surface oxide film. Therefore, tantalum has important applications in high-tech fields such as electronics, metallurgy, steel, chemical industry, cemented carbide, atomic energy, superconducting technology, automotive electronics, aerospace, medical care and scientific research.

50 percent -70 percent of the world's tantalum is used to make tantalum capacitors in the form of capacitor-grade tantalum powder and tantalum wire. Since the surface of tantalum can form a dense and stable amorphous oxide film with high dielectric strength, it is easy to accurately and conveniently control the anodic oxidation process of capacitors. Capacitors have high capacitance, low leakage current, low equivalent series resistance, good high and low temperature characteristics, long service life, excellent comprehensive performance, and other capacitors are difficult to compare with. It is widely used in communications (switches, mobile phones, pagers, Fax machines, etc.), computers, automobiles, household and office appliances, instrumentation, aerospace, defense and military industries and other industrial and scientific and technological sectors. Therefore, tantalum is an extremely versatile functional material.
