As one of the rare and precious metals, tantalum has very excellent properties. Today, I will introduce the application fields and uses 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 high 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 and health care, and scientific research.
50%-70% of tantalum in the world is used to make tantalum capacitors in the form of capacitor-grade tantalum powder and tantalum wire. Because 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, and at the same time, the sintered block of tantalum powder can obtain a large surface area in a small volume, so tantalum Capacitors have high capacitance, small leakage current, low equivalent series resistance, good high and low temperature characteristics, long service life, excellent comprehensive performance, and other capacitors are difficult to match. 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 technological sectors. Therefore, tantalum is an extremely versatile functional material.
Detailed explanation of the use of tantalum
1: Tantalum carbide, used in cutting tools
2: Tantalum lithium oxide, used in surface acoustic waves, mobile phone filters, hi-fi and televisions
3: Tantalum oxide: lenses for telescopes, cameras, and mobile phones, X-ray films, inkjet printers
4: Tantalum powder, used in tantalum capacitors in electronic circuits.
5: Tantalum plates, used for chemical reaction equipment such as coatings, valves, etc.
6: Tantalum wire, tantalum rod, used to repair skull board, suture frame, etc.
7: Tantalum ingots: used for sputtering targets, superalloys, computer hardware drive discs and TOW-2 bomb forming projectiles
From the perspective of many daily products we come into contact with, tantalum can be used to replace stainless steel, and its service life can be dozens of times longer than stainless steel. In addition, in chemical, electronic, electrical and other industries, tantalum can replace the tasks that used to be undertaken by the precious metal platinum, which greatly reduces the required cost.
