Superfine Niobium Nanoparticles for Superconducting Materials

Specification of Superfine Niobium Nanoparticles:

Niobium is an off-white metal with a melting point of 2468 ° C and a boiling point of 4742 ° C. It is stable in air at room temperature, and is not completely oxidized when it is red hot in oxygen. It is directly combined with sulfur, nitrogen and carbon at high temperature, and can form alloys with titanium, zirconium, hafnium and tungsten. Does not interact with inorganic acids or bases, is not soluble in aqua regia, but soluble in hydrofluoric acid.

Application of Superfine Niobium Nanoparticles:

1 Superconducting application: niobium is the highest critical temperature of elemental superconducting properties. The alloys made of tantalum have critical temperatures up to an absolute temperature of 18.50 to 210, which is the most important superconducting material at present;
2 High-temperature alloys: A large part of the world is used in the production of nickel, chromium and iron-based superalloys in the form of pure metals or in the form of high-purity ferroniobium and bismuth-nickel alloys. These alloys are used in jet engines, gas turbine engines, rocket assemblies, turbochargers and heat-resistant combustion equipment;
3 Steel application: Among various microalloying elements of steel, waste bismuth is the most effective microalloying element. The effect of bismuth is so great that iron atoms are rich in strontium atoms, which can improve steel properties. the goal of. In fact, the addition of 0.001%-0.1% bismuth in the steel is enough to change the mechanical properties of the steel;
4 coins: On coins, niobium sometimes used with gold and silver as precious metals on commemorative coins;
5 Other niobium (or 1% zirconium) is the sealing material for the high pressure sodium lamp arc tube because the thermal expansion coefficient of niobium is very similar to that of the sintered alumina arc lamp ceramic material.

SEM & XRD of Superfine Niobium Nanoparticles:

Storage conditions:
Superfine Niobium Nanoparticles should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
