Used in jet engines, alloys with iron, heat resistant equipment, and in jewellery.
One of 5 major refractory metals- metals with very high resistance to heat and wear. (Tungsten, Molybdenum, Rhenium, Tantalum, and Niobium)
Fun Fact! Niobium is named for the Greek goddess of tears, Niobe, who was the daughter of king Tantalus, according to the Royal Society of Chemistry, due to the element’s similarities to tantalum (named for the king).
