The application fields and uses of tantalum are introduced in detail

Tantalum has a series of excellent properties such as high melting point, low vapor pressure, good cold workability, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of the 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%-70% 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 control the anodization process of capacitors accurately and conveniently. 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.

Detailed use of tantalum

1: Tantalum carbide, for cutting tools

2: Tantalum Lithium Oxide, used in surface acoustic waves, mobile phone filters, hi-fi and TV

3: Tantalum oxide: lenses for telescopes, cameras, and mobile phones, as well as X-ray films, inkjet printers

4: Tantalum powder, used in tantalum capacitors in electronic circuits.

5: Tantalum plate, used for chemical reaction equipment such as coating, valve, etc.

6: Tantalum wire, tantalum rod, used to repair skull plate, suture frame, etc.

7: Tantalum ingots: used for sputtering targets, superalloys, computer hardware drive CDs and TOW-2 bomb forming projectiles

From the more daily products we come into contact with, tantalum can be used to replace stainless steel, and the service life can be dozens of times longer than that of stainless steel. In addition, in the chemical, electronic, electrical and other industries, tantalum can replace the tasks that need to be undertaken by the precious metal platinum in the past, so that the required cost is greatly reduced.
