Definition of columbium in English:

columbium

noun kəˈlʌmbɪəmkəˈləmbiəm

old-fashioned term for niobium
Example sentencesExamples
- Most alloying elements, such as chromium, columbium, copper, iron, manganese, molybdenum, tantalum, and vanadium stabilize the phase to the extent that a mixed - phase or an entirely phase alloy can persist down to room temperature.
- In steel alloyed with molybdenum, manganese and columbium, which is use for these pipe-lines, molybdenum raises both strength and toughness.
- Coltan is a contraction of columbium and tantalum; it's found in 3 billion year old mud and without it much of our modern technology could not be made.
- The gas tungsten arc welding process is used for the pure columbium and for the lower strength commercial alloys.
- To eliminate the intergranular corrosion, it is necessary either to reduce carbon to very low levels, or to add titanium and columbium to tie up the carbon and nitrogen.

Origin

Early 19th century: modern Latin, from Columbia, a poetic name for America from the name of Christopher Columbus (see Columbus, Christopher).
