Rare Earth element | Terbium (Tb)

tb

Muna 1843, Karl G. Mosander wekuSweden akawana chinhuterbium kuburikidza nekutsvakurudza kwake pamusoro peyttrium pasi. Kushandiswa kweterbium kunonyanya kusanganisira minda yepamusoro-soro, inova tekinoroji yakadzika uye ruzivo rwakadzama-mapurojekiti, pamwe nemapurojekiti ane zvakakosha zvehupfumi, ane tarisiro yebudiriro inoyevedza. Nzvimbo huru dzekushandisa dzinosanganisira dzinotevera.

(1) Phosphors inoshandiswa seyakasvibira poda activators mumatatu ekutanga phosphors, akadai seterbium activated phosphate matrix, terbium activated silicate matrix, uye terbium activated cerium magnesium aluminate matrix, iyo inoburitsa girinhi mwenje pasi pekunakidzwa.

(2) Magnetic optical kuchengetedza zvinhu, mumakore achangopfuura, terbium yakavakirwa magineti optical zvinhu zvasvika pachiyero chekugadzira chakakura. Magnetic optical discs akagadzirwa achishandisa Tb-Fe amorphous akaonda mafirimu semakomputa ekuchengetedza zvikamu akawedzera simba rekuchengetedza ne10-15 nguva.

(3) Magneto optical girazi, Faraday rotatory girazi rine terbium, chinhu chakakosha pakugadzira rotator, isolators, uye circulators anoshandiswa zvakanyanya mu laser tekinoroji. Kunyanya, kuvandudzwa nekuvandudzwa kweterbium dysprosium ferromagnetostrictive alloy (TerFenol) yakavhura kushandiswa kutsva kweterbium. Terfenol chinhu chitsva chakawanikwa muma1970, nehafu yealloy ichiumbwa neterbium uye dysprosium, dzimwe nguva nekuwedzera kweholmium, uye imwe yese iri iron. Iyi alloy yakatanga kugadzirwa neAmes Laboratory muIowa, United States. Kana Terfenol yaiswa mundima yemagineti, saizi yayo inochinja kupfuura yakajairwa magineti zvinhu, Shanduko iyi inogona kugonesa mamwe chaiwo majeneti mafambiro awanikwe. Terbium dysprosium iron pakutanga yainyanya kushandiswa mu sonar uye yakashandiswa zvakanyanya munzvimbo dzakasiyana siyana, kusanganisira masisitimu ejekiseni remafuta, kudzora kwevharuvhu yemvura, micro positioning, mechanical actuators, mashandiro, uye mapapiro anodzora ndege uye nzvimbo teresikopu.
