Niobium History
Niobium used to be called columbium in the U.S. for some 100 שנים, whereas it was niobium in Europe. It has a complicated history, but suffice it to say that niobium was pretty much “figured out” in the mid-1800s. Around 1950, the International Union of Pure and Applied Chemistry officially adopted niobium as the element’s name, in deference to European usage. שנאמר, you might still find some who refer to it as columbium!
Where Niobium is Found and Utilized
In nature, niobium is almost always found with tantalum. Today it’s found and mined in Brazil and Canada, with enough to last for probably the next five centuries according to experts.
Where is niobium most utilized? That would be in the steel industry. It’s used to create high-strength, low-alloy steels. Niobium is used to increase toughness as well as corrosion resistance.
סוף סוף, niobium is known as one of the five refractory metals, all of which have very high resistance to heat and wear.
