Hello everyone

I think you are talking about Niobium, not Nirobium? It used to be called columbium and may still have that name in parts of the US.

Wikipedia says 90% of it is used in steel production to improve the properties of steel, and the making of superalloys (of steel) so you know some of the end users. It is also used in superconducting devices and in electronics, but not much as you can see.

China imports it because they don't have any deposits of their own.

If you have some to sell, I would talk to some of the purchasing managers at the large steel manufacturers and at least see if they can tell you where they purchase their niobium from. Lacking that, look at the mines that produce the stuff and talk to them. There must be people who broker the stuff... its a pretty small market dominated by the big mines, but someone will know about it.



Hope this helps,
Jon.
