Niobium the 33rd most abundant element in the earth’s crust is a shiny, steel-grey metal, which is soft when pure. Niobium has very similar chemical properties to that of the element directly below it in the Periodic Table, tantalum. These two elements are always found together, their chemical similarities make it difficult to isolate pure niobium without contamination by tantalum.

APPLICATIONS IN METALLURGY

Niobium consumption is dominated by high-strength, low-alloy steels used in automobiles, aircraft and pipelines. Other uses for niobium include heat-resistant and stainless steels for the petrochemical industry, together with cutting and machining tools, well casings and drill pipes. Small amounts of niobium are also added to super-alloys for jet and rocket engines and industrial gas turbines.
