Ferro Niobium for sales

Submitted by News on Mon, 12/10/2018 - 05:59

Ferro Niobium is an important iron niobium alloy, with a niobium content of 60-70%. It is the main source for niobium alloying of HSLA steel and covers more than 80% of the world wide niobium production. The niobium is mined from pyrochlore deposits and is subsequently transformed into the niobium pentoxide Nb2O5.

This oxide is mixed with iron oxide and aluminium and is reduced in an aluminothermic reaction to niobium and iron.
