Yttrium: uses

The following uses for yttrium are gathered from a number of sources as well as from anecdotal comments. I'd be delighted to receive corrections as well as additional referenced uses (please use the feedback mechanism to add uses).

  • YVO4 europium, and Y203 europium phosphors give the red colour in colour television tubes
  • the oxide is used to produce yttrium-iron-garnets, which are very effective microwave filters
  • yttrium iron, aluminum, and gadolinium garnets have interesting magnetic properties. Yttrium iron garnet is also exceptionally efficient as both a transmitter and transducer of acoustic energy
  • yttrium aluminium garnet is a gemstone (simulated diamond)
  • used in laser systems
  • used as a catalyst for ethene polymerization
  • potential use in ceramic and glasses as the oxide has a high melting point and imparts shock resistance and low expansion characteristics to glass
  • increases increase the strengths of alloys of metals such as chromium, aluminium, and magnesium
