Curiyaha dhulka naadir | Terbium (Tb)

tb

Sannadkii 1843 kii, Karl G. Mosander oo u dhashay Iswiidhan ayaa daah furay curiyahaterbium iyada oo loo marayo cilmi-baaris uu ku sameeyay dhulka yttrium. Codsiga terbium inta badan waxay ku lug leedahay beeraha teknoolajiyada sare, kuwaas oo ah tignoolajiyada degdega ah iyo aqoonta mashaariicda goynta degdega ah, iyo sidoo kale mashruucyo leh faa'iidooyin dhaqaale oo muhiim ah, oo leh rajooyin horumarineed oo soo jiidasho leh. Meelaha ugu muhiimsan ee codsiga waxaa ka mid ah kuwan soo socda.

(1) Fosfooraska waxaa loo isticmaalaa sida firfircoonayaasha budada cagaaran ee saddexda fosfoor ee aasaasiga ah, sida terbium activated phosphate matrix, terbium activated silicate matrix, iyo terbium activated cerium magnesium aluminate matrix, kaas oo iftiimiya iftiinka cagaaran hoostiisa.

(2) Qalabka kaydinta indhaha ee magnetic, sannadihii la soo dhaafay, terbium qalabka magnetic optical ee ku salaysan ayaa gaadhay miisaan wax soo saar ballaaran. Saxanadaha magnetic indhaha ee la sameeyay iyadoo la adeegsanayo filimada khafiifka ah ee Tb-Fe iyadoo qaybaha kaydinta kombuyuutarku ay kordhiyeen awoodda kaydinta 10-15 jeer.

(3) Muraayadaha indhaha ee Magneto, galaas wareega ee Faraday oo ay ku jiraan terbium, waa shay muhiim ah oo loogu talagalay soo saarista wareegyada, go'doominta, iyo wareegayaasha si weyn loogu isticmaalo tignoolajiyada laysarka. Gaar ahaan, horumarinta iyo horumarinta terbium dysprosium ferromagnetostrictive alloy (TerFenol) ayaa furay isticmaalka cusub ee terbium. Terfenol waa shay cusub oo la helay sannadihii 1970-aadkii, iyadoo kala badh alwaaxdu ay ka kooban tahay terbium iyo dysprosium, mararka qaarkoodna lagu daro Holmium, inta soo hartayna waa bir. Alaabtan waxaa markii ugu horreysay sameeyay Ames Laboratory ee Iowa, Mareykanka. Marka Terfenol la dhigo goobta magnetic, cabbirkeedu wuu isbeddelaa in ka badan qalabka birlabeedka caadiga ah, isbeddelkani wuxuu awood u siin karaa dhaqdhaqaaqyo farsamo oo sax ah in la gaaro. Birta Terbium dysprosium ayaa markii hore lagu isticmaali jiray sonar waxaana si weyn loogu isticmaalay dhinacyo kala duwan, oo ay ku jiraan nidaamyada shidaalka lagu duro, kontoroolka dareeraha dareeraha ah, meelaynta micro, mishiinnada farsamada, hababka, iyo hagayaasha garabka ee diyaaradaha iyo telescopes-ka hawada sare.
