Tantalum and niobium oxides increase the refractive index of special lenses for high-end cameras or cameras in parking systems. Niobium pentoxide (Nb 2 O 5) in particular is used to increase the refractive index of optical glasses. This allows the production of thinner lenses and can reduce the number of lenses, making the components lighter ...

Tantalum, niobium, and their oxides are important precursor materials, essential for high-temperature alloys and electronic devices. The primary hydrometallurgical extraction technique to extract tantalum and niobium from minerals involves hydrofluoric acid (HF) digestion of the concentrates, followed by solvent extraction as an oxide separation and purification step.

Tantalum usage for cemented carbides is estimated at about 240 tons per annum. Niobium usage for cemented carbides is estimated at about 60 tons per annum. (Note that the above figures include reclaim, estimated at approximately 20%, and are for entire worldwide estimates, excluding the former Soviet Union.)

Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum minerals are oxides, rather than silicates, sulfides or phosphates.

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 ...
