tantalum capacitors

Tantalum powder and tantalum wire are the key materials for making tantalum capacitors, which are widely used in mobile phones, computers, digital products, automobiles, aerospace electronics, and other fields. About 60 percent of the world’s tantalum is used to make tantalum capacitors.

Tantalum and niobium target materials are used in semiconductor devices and liquid crystal display technologies, and niobium oxide, niobium powder, and niobium wire are used in making ceramic and niobium capacitors. About 90% of the world’s niobium is used in the steel industry, and niobium wire is mainly used in the production of high-strength low-alloy steel, stainless steel, heat-resistant steel, clearance steel, carbon steel, tool steel, rail steel, casting steel.

Superalloys can be produced by adding tantalum or niobium to tungsten, molybdenum, nickel, cobalt, vanadium, ferroalloys, or by using tantalum and niobium as bases, which are important structural materials for aerospace engines, ground-based air turbine engines, modern weapons, and harsh industrial environment facilities.

Because of the good superconductivity of niobium and tantalum metal, the addition of niobium and tantalum into the materials used to make wires and cables can greatly reduce the loss of power and thus save power. Tantalum and niobium are excellent materials for acid and liquid metal corrosion resistance, so they can be used in the chemical industry for digesters, heaters, coolers, and various device containers. Besides that, tantalum and niobium metals and their alloys can also be used as reactor shell materials and high-energy physics superconducting devices.
