niobium

How To Use niobium In A Sentence

• The mine in question will be digging for niobium, a rare metal used as a steel alloy to save on weight and thickness, which is more resistant to corrosion and is easier to weld.
• To alleviate this problem, small quantities of elements which are stronger carbide formers than chromium, such as titanium or niobium are commonly added.
• Previous attempts to lower the switching temperature have incorporated low levels of elements such as tungsten, molybdenum, niobium and fluorine.
• Many contemporary chemists believed niobium and tantalum were the same elements until 1844 and later 1866 when researchers showed that niobic and tantalic acids were different compounds.
• Niobium is a relatively inert element, although it does react with oxygen and concentrated acids at high temperatures.
• The refractory metals include niobium (also known as columbium), tantalum, molybdenum, tungsten, and rhenium.
• Likewise, we could explain the known properties of Earth's core by an alloy of niobium but choose not to do so because a much more abundant element - iron - can do the job.
• Titanium increases the efficiency of niobium because it combines with the nitrogen-forming titanium nitrides, thus preventing the formation of niobium nitrides.
• Certain strong carbide formers, notably niobium, titanium and vanadium, have effects on tempering out of proportion to their concentration.
• Vanadium, molybdenum, niobium, titanium, chromium, nickel, manganese are but a few of the many metals which make their way into steel to yield alloys with special properties.
