Application of tantalum material niobium material

Tantalum high temperature resistance, good strength and rigidity, is the production of vacuum high temperature furnace with heating components, insulation components and loading vessels of high quality materials. The main purpose of tantalum is to make capacitors. Tantalum capacitors are currently the best performance capacitors. Tantalum wire is used as the anode lead of tantalum capacitors, because tantalum has excellent physical and chemical properties, its high melting point, small thermal expansion coefficient, excellent toughness and ductility, especially its excellent corrosion resistance, hydrochloric acid, concentrated nitric acid and "aqua regia" have no reaction. Tantalum wire has also been important in medical applications, because of its biocompatibility, human muscles can grow on it, so it can be used to compensate muscle tissue and suture nerves and tendons.
Tantalum niobium is a high-quality acid and alkali resistance and liquid metal corrosion materials, in the chemical industry can be used to make digesters, heaters, coolers, a variety of utensils and devices.
The metal niobium has high temperature resistance and high strength, and still has sufficient strength, good plasticity and thermal conductivity above 1000 ℃. Superconductivity is the best at very low temperatures, such as around minus 260 ℃, and its resistance is close to zero. It is currently the most important superconducting material.
Niobium wire and niobium-zirconium alloy wire are widely used in the fields of chemistry, electronics, aviation and aerospace due to their high melting point, corrosion resistance and good cold workability. The addition of zirconium to niobium can significantly improve the oxidation resistance and strength of the material, and niobium and niobium-zirconium alloy wires are widely used in the manufacture of high-pressure sodium lamps and electrolytic capacitor anode leads.
