Yttrium was discovered by Johann Gadolin in 1794 and was first isolated by Carl Gustav Mosander in 1840. The name yttrium originated from a Swedish village near Vaxholm called Yttbery, where it was discovered.
Yttrium (atomic symbol: Y, atomic number: 39) is a Block D, Group 3, Period 5 element with an atomic weight of 88.90585. The number of electrons in each of yttrium's shells is [2, 8, 18, 9, 2], and its electron configuration is [Kr] 4d1 5s2. The yttrium atom has a radius of 180 pm and a Van der Waals radius of 219 pm.
Yttrium is a transition metal, similar to the lanthanides. It is found in most rare-earth minerals. In its elemental form, yttrium has a silvery-white metallic appearance. Yttrium has the highest thermodynamic affinity for oxygen of any element. Yttrium is not found in nature as a free element and is almost always found combined with the lanthanides in rare earth minerals. While not part of the rare earth series, it resembles the heavy rare earth, sometimes referred to as the "yttrics". Another unique characteristic derives from its ability to form crystals with useful properties.
Yttrium has been widely used in various fields. For example, the most important use of yttrium is in making phosphors. Yttrium oxide (Y2O3) and yttrium orthovanadate (YVO4) are both combined with europium to produce the red phosphor used in televisions set cathode ray tube (CRT) displays and in LEDs. Yttrium is also used as an additive in alloys to increases the strength of aluminum and magnesium alloys. Yttrium oxide is the host lattice for producing phosphors used in colored televisions and LEDs. Yttrium is also used for producing a variety of synthetic garnets with different applications such as microwave filters, acoustic energy transmitters, and transducers. Yttrium can be used to produce powerful pulsed lasers and superconductors. In the biomedical field, yttrium is used in cancer treatment drugs, rheumatoid arthritis medicines, and surgical supplies..
Small amounts of yttrium can reduce the grain sizes of chromium, molybdenum, titanium, and zirconium. Yttrium is also used to enhance the strength of aluminum and magnesium alloys. The addition of yttrium to alloys can generally add resistance to high-temperature recrystallization and high-temperature oxidation. Our Yttrium products:
