Niobium and tantalum - pubs.er.usgs.gov

Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines ...

Tantalum Processing | TIC

The cleaned titanium-niobium-tantalum oxichloride gas is then cooled to a liquid and distilled to separate out low-boiling titanium chloride gas, whereafter the niobium-tantalum oxichloride gas is further chlorinated to produce NbCl 5 and TaCl 5. These chlorides are fractionally distilled and the niobium chloride subsequently reacted with steam ...

Niobium Extraction, Refining & Production | TIC

Niobium oxide (Nb 2 O 5) is generally the starting chemical for the production of other compounds, such as niobium chloride (NbCl 5), niobium carbide (NbC), or lithium niobate (LiNbO 3). Niobium metal is produced by the aluminothermic reduction of the oxide followed by electron beam refining.
