Yttrium - here's that village Ytterby again

Yttrium is yet another element named after the village of Ytterby and is important in the development of high temperature superconductors, says Allan Blackman from AUT in ep 96 of Elemental.Here we go again - yet another element named after the Swedish village of Ytterby with a suitably tortuous extraction process, although surprisingly it is actually not a lanthanoid; it is a transition metal.It is used in camping gas mantles along with thorium, is added to cast iron to make it more ductile, and appears in alloys used in cutting tools, bearings and jet engines.When used with ytterbium, barium, copper and oxygen, it creates a high-temperature superconductor that operates at much warmer temperatures than most superconductors.Kiwi scientists Jeff Tallon and Bob Buckley are at the forefront of high temperature superconductor research, says Professor Allan Blackman from the Auckland University of Technology, in episode 96 of Elemental.Go to this episode on rnz.co.nz for more details
