Niobium demand and superconductor applications: An overview

Electrochemical Studies on Reduction of Solid Nb[sub 2]O[sub 5] in Molten CaCl[sub 2]-NaCl Eutectic

“…It is also employed in the fields of applied superconductivity and structural materials production. [1][2][3] At present, the existing commercial processes for producing niobium metal include the aluminothermic reduction of Nb 2 O 5 , the carbothermic reduction of Nb 2 O 5 , and the sodium reduction of K 2 NbF 7 . [4][5][6][7][8][9][10] In addition, a number of the processes based upon electrolytic reduction of Nb 2 O 5 , NbCl 5 , and K 2 NbF 7 in molten salts have been also investigated extensively, although as yet none of these electrowinning processes has been commercialized for niobium production.…”

Competition in the International Niobium Market: An Econometric Study

“…Niobium (Nb) is a chemical element with a high melting point that is corrosion resistant and exhibits superconductivity properties at low temperatures. Those characteristics, among others, confer important industrial applications mainly in special steels [see Laverick (1988)]. Ferro-niobium is an iron niobium alloy used to add niobium to steel to obtain greater mechanical resistance, lighter weight and reduced cost.…”

“…a) Niobium has an important role in steel alloys for the aerospace industry and future potential for the industry's superconductors. Although there are more descriptive studies reporting the main supply and demand characteristics of the niobium sector [see Laverick (1988). Campanário (1991) and Cunningham (2000)], there is a gap in the literature in terms of quantitative economic efforts.…”
