Lisebelisoa tsa Rare Earth Elements

Liindasteri tse thehiloeng, tse kang li- catalyst, tse etsang likhalase, tse bonesang le tsa metallurgy, li 'nile tsa sebelisa likarolo tse sa tloaelehang tsa lefatše ka nako e telele. Liindasteri tse joalo, ha li kopantsoe, li etsa karolo ea 59% ea kakaretso e sebelisoang lefatšeng ka bophara. Hona joale libaka tse ncha, tse holang haholo, joalo ka li-alloys tsa betri, li-ceramics, le limakete tse sa feleng, le tsona li sebelisa likarolo tse sa tloaelehang tsa lefatše, tse etsang tse ling tse 41%.

Lefapheng la tlhahiso ea likhalase, li-oxide tsa lefatše tse sa tloaelehang ke khale li ithutoa. Haholo-holo, hore na thepa ea khalase e ka fetoha joang ka ho eketsoa ha metsoako ena. Rasaense oa Lejeremane ea bitsoang Drossbach o ile a qala mosebetsi ona lilemong tsa bo-1800 ha a ne a e-na le tokelo ea molao le ho etsa motsoako oa li-oxide tsa lefatše tse sa tloaelehang bakeng sa ho senya khalase.

Le hoja e ne e le ka mokhoa o sa tloaelehang le li-oxide tse ling tse sa tloaelehang tsa lefatše, ena e ne e le tšebeliso ea pele ea khoebo ea cerium. Cerium e ile ea bontšoa e le e babatsehang bakeng sa ho monya ha ultraviolet ntle le ho fana ka 'mala ka 1912 ke Crookes oa Engelane. Sena se etsa hore e be molemo haholo bakeng sa likhalase tsa mahlo tse sireletsang.

Erbium, ytterbium, le neodymium ke li-REE tse sebelisoang haholo likhalaseng. Puisano ea mahlo e sebelisa erbium-doped silica fiber haholo; ts'ebetso ea thepa ea boenjiniere e sebelisa ytterbium-doped silica fiber, le lasers ea khalase e sebelisoang bakeng sa fusion ea inertial e sebelisa neodymium-doped. Bokhoni ba ho fetola thepa ea fluorescent ea khalase ke e 'ngoe ea litšebeliso tsa bohlokoahali tsa REO ka khalase.

Thepa ea Fluorescent e tsoang ho Rare Earth Oxides

E ikhetha ka tsela eo e ka bonahalang e tloaelehile ka tlas'a leseli le bonahalang 'me e ka ntša mebala e hlakileng ha e thabisoa ke maqhubu a itseng a maqhubu, khalase ea fluorescent e na le likopo tse ngata ho tloha ho litšoantšo tsa bongaka le lipatlisiso tsa biomedical, ho hlahloba mecha ea litaba, tracing le li-enamel tsa khalase ea bonono.

Fluorescence e ka tsoela pele ho sebelisa li-REO tse kentsoeng ka kotloloho ka har'a matrix ea khalase nakong ea ho qhibiliha. Lisebelisoa tse ling tsa khalase tse nang le seaparo sa fluorescent feela hangata li hlōleha.

Nakong ea tlhahiso, ho kenngoa ha li-ion tsa lefats'e tse sa tloaelehang mohahong ho fella ka khalase ea optical fluorescence. Li-electrone tsa REE li phahamisetsoa boemong ba thabo ha mohloli oa matla o kenang o sebelisoa ho hlasimolla li-ion tsena tse sebetsang ka ho toba. Ho ntšoa ha leseli la bolelele bo bolelele ba maqhubu le matla a tlase ho khutlisetsa boemo ba thabo fatše.

Ts'ebetsong ea indasteri, sena se bohlokoa haholo kaha se lumella li-microspheres tsa inorganic glass hore li kenngoe ka har'a beche ho khetholla moetsi le nomoro ea lotho bakeng sa mefuta e mengata ea lihlahisoa.

Ho tsamaisoa ha sehlahisoa ha ho amehe ke li-microspheres, empa 'mala o itseng oa leseli o hlahisoa ha leseli la ultraviolet le khanyetsa holim'a batch, e leng se lumellang ho tseba hantle hore na thepa e tsoa hokae. Sena se ka khoneha ka mefuta eohle ea thepa, ho kenyeletsoa phofo, polasetiki, lipampiri le maro.

Mefuta e mengata haholo e fanoa ka har'a li-microspheres ka ho fetola palo ea liparamente, joalo ka karolelano e nepahetseng ea REO e fapaneng, boholo ba likaroloana, kabo ea boholo ba likaroloana, sebopeho sa lik'hemik'hale, thepa ea fluorescent, 'mala, thepa ea khoheli le radioactivity.

Ho boetse ho na le molemo ho hlahisa li-microspheres tsa fluorescent ho tloha khalase kaha li ka sebelisoa ho ea ka likhato tse fapaneng ka li-REO, li mamella mocheso o phahameng, likhatello tse phahameng, 'me ha li na lik'hemik'hale. Ha ho bapisoa le li-polymers, li phahametse libakeng tsena kaofela, e leng se li lumellang hore li sebelisoe libakeng tse tlaase haholo lihlahisoa.

Sollubility e batlang e le tlase ea REO ka khalase ea silika ke moeli o le mong o ka bang teng kaha sena se ka lebisa ho thehoeng ha lihlopha tse sa tloaelehang tsa lefats'e, haholo-holo haeba motsoako oa doping o le moholo ho feta tekano ea solubility, 'me o hloka khato e khethehileng ho thibela ho thehoa ha lihlopha.
