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. 89Y is the only stable isotope, and the only isotope found in the Earth's crust. -Wikipedia Quarter and scale not included ProductSiteLaunchDate : 2019-06-22T02:24:20.692Z SupplierDeclaredDgHzRegulation : not_applicable UnspscCode : 41000000
