Rare earth metal pure Yttrium 99.9% ingot in small pellet 10mm per piece
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element. Y is the only stable isotope, and the only isotope found in the Earth's crust.

Application
Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation.
Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals. It is also used in white LED lights.
Yttrium oxide is added to the glass used to make camera lenses to make them heat and shock resistant. It is also used to make superconductors. Yttrium oxysulfide used to be widely used to produce red phosphors for old-style colour television tubes.
The radioactive isotope yttrium-90 has medical uses. It can be used to treat some cancers, such as liver cancer.
