Niobium Seamless Pipe
Introduction:
Niobium is a lustrous, grey, ductile, paramagnetic metal in periodic table
The metal takes on a bluish tinge when exposed to air at room temperature for extended periods.Despite presenting a high melting point in elemental form (2,468 °C), it has a low density in comparison to other refractory metals. Furthermore, it is corrosion resistant, exhibits superconductivity properties, and forms dielectric oxide layers. These properties especially the superconductivity are strongly dependent on the purity of the niobium metal. When very pure, it is comparatively soft and ductile, but impurities make it harder.
The atoms of niobium is slightly less electropositive and smaller than the atoms of its predecessor in the periodic table, zirconium, while it is virtually identical in size to the heavier tantalum atoms as a consequence of the lanthanide contraction. As a result, niobium's chemical properties are very similar to the chemical properties of tantalum, which appears directly below niobium in the periodic table. Although its corrosion resistance is not as outstanding as that of tantalum, its lower price and greater availability make niobium attractive for less exact uses such as linings in chemical plants
