CAS 7440-03-1 Nb Niobium Refractory Metal Powder used in various
Brief Description of Niobium Powder
Niobium, formerly known as columbium, is a chemical element with symbol Nb (formerly Cb) and atmoic number 41.
It is a soft, grey, crystalline, ductile transition metal, often
found in the minerals pyrochlore and columbite.
Niobium is used in various superconducting materials. These superconducting alloys,also containingtitanium and tin,are widely used in the superconducting magnets of MRI scanners.
Other applications of niobium include welding, nuclear industries,
electronics, optics, numismatics, and jewelry.
In the last two applications, the low toxicity and iridescence
produced by anodization are highly desired properties.
Specification of Niobium Powder
Application of Niobium Powder
1. Used for Super hard materials, carbide, capacitors, powder
metallurgy, refractory alloy of gold.
2. Used as an alloying addition and used in the production of
welding electrodes, refractory.
3. Also can be used in the manufacture of high temperature ceramic.
Performance of Niobium Powder
1. The dense oxide film on surface has one-way conductive metal
2. Niobium powder for stainless steel has a high melting point,
good corrosion resistance etc.
Storage condition of Niobium Powder
Carefully keep away from moist and damp. Store in dry and
1: May I get one sample before placing order?
Re: Yes, we'd like to provide sample for you. For those normal
products, you just need to bear the freight; for those high value
