Chlorination of niobium and tantalum ore ScienceDirect

The chlorination rate of Ta and Nb ore, columbite, was found to be faster than that of pure oxides. Direct chlorination became significant >500C. The reaction involves breakdown of the structure of the columbite particles. Chlorides of Fe and Mn were volatilized and crystals high in Nb and Ta content were grown from the gaseous phase.

Niobium

Niobium

Niobium, formerly known as columbium, is a chemical element with the symbol Nb and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure Niobium has a hardness similar to that of pure titanium, and it has similar ductility to iron. Niobium oxidizes in the earth's atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel. Niobium is often

Niobium (Columbium) Chemical and Physical Properties

Niobium is used in arc welding rods for stabilized grades of stainless steel. It is also used in advanced airframe systems. Superconductive magnets are made with Nb Zr wire, which retains superconductivity in strong magnetic fields. Niobium is used in lamp filaments and to make jewelry. It is capable of being colored by an electrolytic process.
