Specification

Application

1. Money: On coins, gold and silver and ultrafine niobium  nanopowder are sometimes used together as a precious metal in the coins

2. Super alloys: a large portion of niobium to pure metal form or in the form of high-purity niobium and niobium iron-nickel alloy, used in the production of nickel, chromium and iron-base super alloys world. These alloys can be used in jet engines, gas turbine engines, rocket components, turbochargers and heat of combustion equipment;

3. Steel Application: in various micro-alloying elements in steel, niobium waste is the most effective micro-alloying elements, niobium role is so great that the iron atoms are rich in niobium atom, we can achieve performance improvements Steel purposes. Actually Steel added 0.001% -0.1% niobium, is enough to change the mechanical properties of steel;

Storage

Put it in a tightly sealed container and store in a cool, dry place.

Stability

It is stable at room temperature in the air, and begins to oxidize at 200°C to form a dense oxide film.

Avoid oxides, alkalis, and halogens. Niobium has strong corrosion resistance to acid.
