Niobium de applications

In the chemical industry, niobium is a high-quality material resistant to acid and liquid metal corrosion, and can be used to make digesters, heaters, coolers and so on.In addition, niobium acid is an important catalyst.
Niobium is also used in the foundry industry, where its main roles are to form hard carbides (which are good for wear resistance) and to change the shape and size of graphite flakes, and is thus often used in the manufacture of automobile cylinder heads, piston rings and brake pads, among other things. In addition, niobium is sometimes used in commemorative coins along with gold and silver.
Niobium helps to increase the light transmission properties of lenses and is therefore also used in the manufacture of lenses for the optical industry.
Niobium is also used in the lighting industry, e.g. alloys of niobium with 1% zirconium are used to make precision brackets for highly efficient, high-strength sodium vapor street lamps, giving these small parts high thermal strength, excellent formability, and resistance to sodium vapor corrosion.
