Origin of 'niobium'

Main points about word origin

  • The name 'niobium' comes from Niobe, a mythological character who was the daughter of Tantalus.
  • Initially discovered in 1801, niobium was originally referred to as 'columbium' in honor of Christopher Columbus before being renamed.

The name niobium is derived from Niobe, a character in Greek mythology, who was the daughter of Tantalus. The mythological tie is fitting, as niobium was discovered in 1801 by the English chemist Charles Hatchett as a new element from columbite, which had previously been named after the mythological figure Tantalus (the element tantalum). Thus, niobium and tantalum share a historical connection, as both were isolated from similar mineral sources. The name was officially adopted in 1949, but the metal itself had been used in small quantities in various applications long before then. Additionally, niobium's unique properties, including its high melting point and resistance to corrosion, have made it increasingly important in modern technologies, particularly in aerospace and electronics.
