Yttrium was discover in the late 18th century , but only during the retiring few decade has this piano , silvery metal found far-flung use — in chemistry , physics , figurer engineering , push , medicine and other fields .
On the Periodic Table of Elements , Y is among thetransition metal , which admit some more well - known elements , such as silver and iron . Transition alloy incline to be potent but pliable , which is why some of them , such as copper and nickel , are widely used for wires . Yttrium wires and rod are also used in electronics and solar energy . Yttrium is also used in optical maser , ceramic , photographic camera lens , and heaps of other items .
A piece of yttrium.
Yttrium is also one of the rare - land elements . Despite their name , rare - earth chemical element are rather rich around the universe . The 17 rare - earth elements include yttrium , atomic number 21 and 15 lanthanides ( the metallic elements with atomic number 57 through 71 ) . They have become indispensible in the manufacturing of cell phones and other technology .
However , yttrium is seldom used on its own . alternatively , investigator use it to form chemical compound , such as yttrium barium copper oxide ( YBCO ) — which helped usher in a new phase ofhigh - temperature superconductivity research . Yttrium is also added to alloy alloys to help improve resistance to erosion and oxidation .
" Like many elements , you wo n’t find Y as an element or chemical compound in general employment , " said Joseph Gambogi , mineral commodity medical specialist with the U.S. Geological Survey ’s National Minerals Information Center . " Rather , yttrium and its compounds are added to other materials to enhance properties of other materials . "
Electron configuration and elemental properties of yttrium.
Mas Subramanian , a professor of material scientific discipline at Oregon State University , concord . " In all of these case , Y is used to make the social system stable . " Subramanian and his squad at OSU combined Y with indium and manganese to constitute a graphic blue paint called YinMn Blue . " Manganese is really what gave it coloring , but yttrium help carry the structure together , " he told Live Science .
Just the facts
History
In 1787 , a Swedish US Army deputy and part - time chemist named Carl Axel Arrhenius find an strange black rock when exploring a quarry near Ytterby , a modest town near Sweden ’s cap metropolis , Stockholm . Thinking he had discovered a new mineral turn back tungsten , Arrhenius place the specimen to Johan Gadolin , a mineralogist and druggist in Finland , for analysis .
Gadolin isolated the Y within the mineral , which was later named gadolinite in his award . Yttrium was named for Ytterby .
In 1843 , a Swedish pharmacist named Carl Gustaf Mosander studied atomic number 39 sample distribution and discovered they contained three oxides . At the time they were called yttria , erbia and terbia . They are now known as snowy yttrium oxide , yellow terbium oxide , and rose - colour erbium oxide , respectively . A fourth oxide , ytterbium oxide , was identify in 1878 .
Sources of yttrium
Though yttrium was discovered in Scandinavia , it is far more bountiful in other land . China , Russia , India , Malaysia and Australia are the leave producer of yttrium . In April 2018 , scientist discovered what they think is amassive deposit of rare ground alloy , include Y , on a small Japanese island called Minamitori Island .
Yttrium can be found in most of the rarefied earth minerals , but has never been discovered in the Earth ’s crust as a freestanding constituent . Lunar rocks get together during the Apollo lunation missions contain yttrium . The human body also hold yttrium in bantam sum , usually concentrated in the liver , kidney , and bones .
Uses of yttrium
Before the geological era of matted - screen televisions , telly lot contained heavy cathode ray electron tube , which were large shabu tube that projected images on the screen . atomic number 39 oxide , doped with the elementeuropium , bring home the bacon the red color on trillion of color - television set set .
Yttrium oxide ( yttria ) is summate to zirconium oxide ( zirconia ) to make an alloy that stabilizes the crystal structure of zirconia , which normally changes with temperature . " fundamentally , yttria lock in the three-dimensional structure of zirconia , creating a ceramic with exceptionally in high spirits toughness that is worthy for use at very gamey temperature , " Gambogi said . " This type of ceramic is used in a variety of applications programme from electronics to caloric barrier coatings onjet enginesto aesculapian implant . "
celluloid garnet made with an yttrium - aluminum complex were commonly sold in the 1970s as simulated diamonds and other gemstones , but they eventually grant mode to the three-dimensional zirconia , Gambogi said . These twenty-four hour period , Y aluminum garnet ( YAG ) are used as the crystals that amplify light in industrial optical maser . atomic number 39 iron garnets are used for microwave oven filter , as well as in radar and communication engineering .
" Although yttrium is found in a multitude of applications , the largest end uses are ceramic and phosphors , " Gambogi differentiate Live Science . " Lesser amounts are used in metallurgy , glass shining and additives , and catalysts . … There also are a the great unwashed of electronic coating , but atomic number 8 sensing element are an especially significant use . "
atomic number 39 is wide used to produce phosphors that are used in cellphone phones and tumid presentation screens as well as general kindling . Yttrium in red phosphors in color boob tube subway precede to widespread use in the sixties and ' 70 . Fluorescent tubes ( linear and compact ) habituate importantly more Y per James Watt than LED bulbs .
The radioactive isotope yttrium-90 is used inradiation therapyto do by liver cancer and some other cancer .
Current research
Subramanian said that yttrium was easy to work with and less expensive than many other elements . For example , researchers are using atomic number 39 instead of the much more expensive atomic number 78 to developfuel cells . Scientists at Chalmers University of Technology and Technical University of Denmark are using Y and other rare ground alloy in nanoparticle build , which may one day eliminate the need for dodo fuels and supercharge the efficiency of shelling - power motorcar .
Yttrium - base superconductivity research continues around the populace . Breakthroughs are being made in levitation trains and charismatic resonance imagination ( MRI ) skim in wellness concern . In 1987 , when researchers at the University of Houston were wait for a metal that would facilitate superconductivity at eminent temperatures , they turned to yttrium . mellow - temperature superconductivity had been limited to negative 420 degrees Fahrenheit ( minus 251 Celsius ) . Physicist Paul Chu and his squad at the University of Houston discovered that a compound of yttrium , barium and pig oxide ( known as Yttrium 123 ) could facilitate superconductivity at about minus 300 point F ( minus 184.4 degrees C ) . They had created a fabric that could be chill with liquid atomic number 7 , which would significantly lower the monetary value of future superconductivity applications .
Subramanian is work with key and plastics companies to develop more USA of YinMn blue sky . The potential enjoyment are due in big part to yttrium ’s unique properties . " It ’s a light - weight unit element , so you may have more volume without tote up system of weights , " he said . " That ’s very helpful for blusher . Yttrium is an amazing element . "
