Rare Earth element | Terbium (Tb)

Mu 1843, Karl G. Mosander wa ku Sweden anapeza chinthuchoterbium kudzera mu kafukufuku wake pa yttrium lapansi. Kugwiritsiridwa ntchito kwa terbium makamaka kumakhudza magawo apamwamba kwambiri, omwe ali ndi luso lamakono komanso mapulojekiti odziwa zambiri, komanso mapulojekiti omwe ali ndi phindu lalikulu lachuma, omwe ali ndi chiyembekezo chotukuka. Magawo akuluakulu ogwiritsira ntchito ndi awa.

(1) Phosphors amagwiritsidwa ntchito ngati oyambitsa ufa wobiriwira mu phosphors zitatu zazikulu, monga terbium activated phosphate matrix, terbium activated silicate matrix, ndi terbium activated cerium magnesium aluminate matrix, yomwe imatulutsa kuwala kobiriwira pansi pa chisangalalo.

(2) Maginito optical yosungirako zipangizo, m'zaka zaposachedwapa, terbium zochokera maginito kuwala zipangizo zafika pamlingo waukulu kupanga. Maginito opanga mafilimu opangidwa ndi Tb-Fe amorphous mafilimu ochepa kwambiri monga zosungirako makompyuta zawonjezera mphamvu zosungirako maulendo 10-15.

(3) Magneto kuwala galasi, Faraday rotatory galasi munali terbium, ndi mfundo zofunika popanga rotator, zodzipatula, ndi circulator ntchito kwambiri mu luso laser. Makamaka, chitukuko ndi chitukuko cha terbium dysprosium ferromagnetostrictive aloyi (TerFenol) watsegula ntchito zatsopano terbium. Terfenol ndi zinthu zatsopano zomwe zinapezeka m'ma 1970, ndi theka la aloyi wopangidwa ndi terbium ndi dysprosium, nthawi zina ndi kuwonjezera kwa holmium, ndi zina zonse kukhala chitsulo. Aloyiyi idapangidwa koyamba ndi Ames Laboratory ku Iowa, United States. Terfenol ikayikidwa mu gawo la maginito, kukula kwake kumasintha kuposa zida wamba maginito, Kusintha kumeneku kutha kupangitsa kuti mayendedwe olondola azitha kuchitika. Terbium dysprosium iron poyamba inkagwiritsidwa ntchito mu sonar ndipo yakhala ikugwiritsidwa ntchito kwambiri m'magawo osiyanasiyana, kuphatikiza makina ojambulira mafuta, kuwongolera ma valve amadzimadzi, ma micro positioning, makina oyendetsa makina, makina, ndi owongolera mapiko a ndege ndi ma telescope amlengalenga.
