Properties of yttrium

Here is a list of some physical properties and chemical properties of yttrium.

Physical properties of yttrium

  • Yttrium is solid metal having a silvery white metallic appearance.
  • Out of all the isotopes of yttrium, the stable isotope is 89Y.
  • Yttrium has an atomic mass 88.906 u and its density is 4.472 g/cm3.
  • The melting point and boiling point of the yttrium metal is 1799 K and 3203 K respectively.

Chemical properties of yttrium

  • Yttrium forms a thin oxide layer in the air and this layer prevents it from further oxidation.
  • When yttrium reacts with water, it forms yttrium hydroxide and it liberates hydrogen gas during this reaction.
  • If the powdered form of yttrium is heated in air, then it will ignite easily.

Uses of yttrium

Here are some uses of the yttrium element.

  • Yttrium is largely used in ceramic industries.
  • In old color TVs, the yttrium element was used to get the red color on the screen.
  • Yttrium is also used as an alloying element with other metals, which gives improved properties like resistance to oxidation, resistance to corrosion, etc.
  • Yttrium is also used in making camera lenses, computer screens, etc.
  • Nd:YAG lasers contain yttrium element. Yttrium is used to amplify the laser light.
  • Yttrium is also present in YBCO (yttrium barium copper oxide), which is a high temperature superconductor.
  • Liver cancers can also be treated with the use of radioactive isotope of yttrium (i.e 90Y).
  • Yttrium is also used as a catalyst in polymerization of ethylene.
