Niobium
    Publish time 2019-07-27 12:27    

Atomic Symbol:    Nb

Atomic number:    41

Melting point:     2468 DC

Density:         8.57g/cm3


Niobium is one of refractory metal,it is a soft and ductile metal, shiny and white in colour. However when exposed to air at room temperature takes on a bluish tint. It has a high melting point and consequently is used in high temperature engineering systems such as those used in the Gemini space program. Niobium is used in the nuclear industry since it has a low capture cross section for thermal neutrons. When combined with zirconium it has superconductive properties and hence some superconductive magnets contain Nb-Zr alloy wire. It has also been used for body jewellery due to its attractive shiny blue tint.

Niobium is extremely corrosion resistant in demanding applications. One of the common uses for niobium is overhead condensers and related heat/recovery sections of nitric acid facilities. Its advantages include exceptional durability, excellent heat transfer properties, years of performance without lost production and eliminating the added expense of back-up equipment.we supply as follows,
