Niobium fabrication
Niobium belongs to the group of refractory metals. Refractory metals are metals that have a higher melting point than platinum (1 772 °C). In refractory metals, the energy binding the individual atoms together is particularly high. Refractory metals have a high melting pointcoupled with a low vapor pressure, high modulus of elasticity and high thermal stability. Refractory metals are also characterized by a low coefficient of thermal expansion. Compared to other refractory metals, niobium has a relatively low density of only 8.6 g/cm3
Niobium is located in the same period as molybdenum in the periodic table. Its density and melting point are therefore comparable to those of molybdenum. In the same way as tantalum, niobium is prone to hydrogen embrittlement. The heat treatment of niobium therefore takes place in a high vacuum and not in a hydrogen atmosphere. Both niobium and tantalum also offer a high level of resistance against all acids and good formability.
At -263.95 °C, niobium has the highest transition temperature of all elements. Below this temperature, niobium is superconducting. And what is more, niobium boasts a very special range of properties:
