The chemical properties of niobium tubes are very stable!

Niobium tubes are of excellent quality and can quickly form a surface oxide film in almost any environment and carefully cover it on its metal substrate. The oxide film is thin and dense, and is impermeable to almost all media. , and if there is any damage, you can take the initiative immediately.

Because of such an excellent protective film, tantalum has superior corrosion resistance.
Except for fluorine, hydrofluoric acid, acidic sols containing fluoride ions, fuming nitric acid and strong alkali, tantalum will not be corroded in most media. The following table compares the corrosion resistance of tantalum with titanium and zirconium.

Niobium is a gray-white metal with a density of 8.57, a melting point of 2468℃, and a boiling point of 4742℃. It has excellent properties such as high specific gravity, high melting point, high boiling point, high strength, fatigue resistance, anti-deformation, anti-corrosion, thermal conductivity, superconductivity, unipolar conductivity and gas absorption. The chemical properties of niobium are very stable. It forms a fine oxide film on the surface at room temperature to prevent further oxidation. It directly combines with sulfur, nitrogen and carbon at high temperatures and can form alloys with titanium, zirconium, hafnium and tungsten.
