As one of the rare and precious metals, tantalum has relatively low popularity and is generally not exposed in daily life, or is not known to be tantalum. Today, we will introduce the application fields and uses of tantalum to everyone.

Tantalum has a series of excellent properties such as high melting point, low steam 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 engineering, hard alloys, atomic energy, superconducting technology, automotive electronics, aerospace, healthcare, and scientific research.

50% -70% of tantalum in the world is used in the form of capacitor grade tantalum powder and tantalum wire to make tantalum capacitors. Due to the ability to form a dense and stable amorphous oxide film with high dielectric strength on the surface of tantalum, it is easy to accurately and conveniently control the anodic oxidation process of capacitors. At the same time, tantalum powder sintering can obtain a large surface area in a very small volume. Therefore, 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 are difficult to compare with other capacitors, It is widely used in communication (switches, mobile phones, pagers, fax machines, etc.), computers, automobiles, household and office appliances, instruments and meters, aerospace, defense and military industries, and other industrial and technological departments. Therefore, tantalum is an extremely versatile functional material.

Detailed explanation of the uses of tantalum

1: Tantalum carbide: used for cutting tools

2: Tantalum lithium oxide: used for surface acoustic waves, mobile phone filters, high fidelity audio systems, and television

3: Tantalum oxide: used for lenses and X-ray films in telescopes, cameras, and mobile phones, inkjet printing machines

4: Tantalum powder: Used for tantalum capacitors in electronic circuits.

5: Tantalum plate: used for chemical reaction equipment such as coatings, valves, etc

6: Tantalum wire and rod: used for repairing skull boards, sewing frames, etc

7: Tantalum ingot: used for sputtering targets, high-temperature alloys, computer hardware drive optical disks, and TOW-2 bomb shaped pellets

From the daily products we come into contact with, tantalum can be used as a substitute for stainless steel, and its lifespan can be increased by dozens of times compared to stainless steel. In addition, in industries such as chemical, electronic, and electrical industries, tantalum can replace tasks previously undertaken by the precious metal platinum, greatly reducing the required costs.
