Ntho e sa tloaelehang ea lefats'e | Terbium (Tb)

tb

Ka 1843, Karl G. Mosander oa Sweden o ile a sibolla elementeterbium ka lipatlisiso tsa hae mabapi le lefats'e la yttrium. Tšebeliso ea terbium haholo-holo e kenyelletsa masimo a theknoloji e phahameng, e leng merero e matla ea theknoloji le tsebo e matla, hammoho le merero e nang le melemo e mengata ea moruo, e nang le litebello tse khahlehang tsa ntlafatso. Libaka tse kholo tsa kopo li kenyelletsa tse latelang.

(1) Phosphors e sebelisoa e le li-activator tse tala tsa phosphors tse tharo tsa mantlha, tse kang terbium activated phosphate matrix, terbium activated silicate matrix, le terbium activated cerium magnesium aluminate matrix, e hlahisang leseli le letala tlas'a ts'oaetso.

(2) Lisebelisoa tsa polokelo ea Magnetic optical, lilemong tsa morao tjena, lisebelisoa tsa terbium tse thehiloeng ho magnetic optical li fihlile tekanyong e kholo ea tlhahiso. Magnetic optical discs e entsoeng ka ho sebelisa lifilimi tse tšesaane tsa Tb-Fe amorphous kaha likarolo tsa polokelo ea k'homphieutha li ekelitse matla a polokelo ka makhetlo a 10-15.

(3) Magneto optical glass, Faraday rotatory glass e nang le terbium, ke lisebelisoa tsa bohlokoa bakeng sa ho etsa li-rotator, isolators, le li-circulator tse sebelisoang haholo theknoloji ea laser. Haholo-holo, nts'etsopele le nts'etsopele ea terbium dysprosium ferromagnetostrictive alloy (TerFenol) e butse lisebelisoa tse ncha tsa terbium. Terfenol ke thepa e ncha e fumanoeng lilemong tsa bo-1970, 'me halofo ea motsoako e entsoe ka terbium le dysprosium, ka linako tse ling ka ho eketsoa ha holmium,' me tse ling kaofela e le tšepe. Alloy ena e qalile ho hlahisoa ke Ames Laboratory e Iowa, United States. Ha Terfenol e kenngoa sebakeng sa khoheli, boholo ba eona bo fetoha ho feta lisebelisoa tse tloaelehileng tsa makenete, Phetoho ena e ka etsa hore metsamao e nepahetseng ea mochini e fihlellehe. Terbium dysprosium iron qalong e ne e sebelisoa haholo ho sonar 'me e se e sebelisoa haholo makaleng a fapaneng, ho kenyeletsoa lisebelisoa tsa ente ea mafura, taolo ea li-valve tsa metsi, boemo ba micro, li-actuator tsa mechine, mechine, le balaoli ba mapheo bakeng sa lifofane le libonela-hōle tsa sebaka.
