yttrium:
Yttrium yog cov khoom siv tshuaj nrog lub cim Y thiab tus lej atomic 39. Nws yog cov hlau hloov pauv nyiaj-rau-nyiaj uas muaj cov tshuaj lom neeg zoo sib xws rau cov lanthanides thiab feem ntau suav tias yog "lub ntiaj teb tsis tshua muaj".
Yttrium yog yuav luag ib txwm ua ke nrog cov lanthanide series nyob rau hauv tsawg lub ntiaj teb cov zaub mov thiab yeej tsis tshwm sim raws li ib tug dawb keeb nyob rau hauv cov xwm.
Nws tsuas yog ruaj khov isotope, 89Y, kuj yog nws qhov tshwm sim nkaus xwb isotope. Qhov tseem ceeb tshaj plaws ntawm kev siv yttrium yog nyob rau hauv kev tsim cov phosphors, xws li liab phosphor siv nyob rau hauv TV cathode ray tube (CRT) qhia thiab LEDs.
Lwm yam kev siv suav nrog kev tsim cov electrodes, electrolytes, hluav taws xob lim, lasers, thiab superconductors; ntau yam kev siv kho mob; thiab raws li kab nyob rau hauv ntau yam ntaub ntawv los txhim kho lawv cov khoom. Yttrium tsis paub txog cov teebmeem lom neeg thiab raug rau yttrium compounds tuaj yeem ua rau mob ntsws rau tib neeg.
