IHolmium, Inombolo ye-Atomic 67, isisindo se-athomu 164.93032, igama element lisuselwa endaweni yokuzalwa komtholi.
Okuqukethwe kweIHolmiumKu-crust yi-0.0001115%, futhi ikhona kanyekanye nezinyeizinto zomhlaba ezingavamileeMonazite naseMhlabeni amaminerali omhlaba. I-Isotope Ezinzile Yemvelo iHolVmium 165 kuphela.
IHolmium iqinile emoyeni owomile futhi oxidize ngokushesha emazingeni okushisa aphezulu;Holmium oxideyaziwa ukuthi inezakhiwo ezinamandla ze-paramagnetic.
Ikhompiyutha yeHalmium ingasetshenziswa njengesengezo sezinto ezintsha ze-ferromagnetic; IHolmium iodide isetshenziselwa ukukhiqiza amalambu we-metal halide -izibani zeHolmium, kanye nama-Laser aseHalmium nawo asetshenziswa kabanzi emkhakheni wezokwelapha.
Ukuthola Umlando
Kutholwe ngu: JL SoRET, PT Cleve
Kutholwe kusuka ngo-1878 kuya ku-1879
Inqubo yokuthola: Itholwe nguJL SoRET ngonyaka we-1878; Kutholwe ngu-PT Cleve ngo-1879
Ngemuva kwe-mossander wahlukanisa umhlaba we-erbium futhii-terbiumUmhlaba kusukaytttriumUmhlaba ngo-1842, ochwepheshe bamakhemikhali abaningi basebenzise ukuhlaziya okubukelayo ukukhomba nokunquma ukuthi bekungeyona ama-oxides amsulwa yento, eyagqugquzela osokhemisi ukuthi baqhubeke nokuzihlukanisa. Ngemuva kokuhlukanisa i-yterterbium oxide futhiScandium oxideUkusuka kwisiteji esinama-oxidized, uCliff uhlukanise ama-oxide amabili ama-ontides ama-1879 ngonyaka we-1879. Omunye wabo ubizwa ngokuthi iHolmium ukukhumbula indawo yokuzalwa, igama lesiLatini lasendulo Holmia eStockholm, eSweden, ngophawu lwasemuva ho. Ngo-1886, enye into yahlukaniswa neHolmium ngeBouvabadrand, kodwa igama leHolmium lagcinwa. Ngokutholwa kweHalmium nezinye izinto zomhlaba ezingandile, esinye isigaba sokuthola okuvela kwesithathu kwezinto zomhlaba ezingavamile sesiphothuliwe

Kuyinsimbi lokho, njenge-dysprosium, ingadonsa ama-neutrons akhiqizwa yi-FLELL FEITY.
Ephendukezelwe ngenuzi, ngakolunye uhlangothi, ukuhlanganiswa okuqhubekayo kwenziwa, ngakolunye uhlangothi, ijubane lokusabela kwe-chain liyalawulwa.
Incazelo Element: I-Energy yokuqala ye-Ionization ingu-6.02 Electron Volts. Ine-luster yensimbi. Kungasabela kancane ngamanzi futhi kuncibilike kuma-dilifu acids. Usawoti uphuzi. I-oxide ho2o2 eluhlaza okotshani. Chaza kumaminerali acid ukukhiqiza usawoti ophuzi we-ion.
Umthombo owengeziwe: Kulungiselelwe ngokunciphisa iHolmium Fluoride HOF3 · 2h2o nge-calcium.
Insimbi yanama ini
IHolmium iyinsimbi emhlophe yesiliva ngokuthungwa okuthambile ne-conductility; Iphuzu elincibilikayo 1474 ° C, Iphuzu elibilayo 2695 ° C, Density 8.7947 g / cm Holmium Meter ³.
IHolmium iqinile emoyeni owomile futhi oxidize ngokushesha emazingeni okushisa aphezulu; IHolmium Oxide yaziwa ngokuthi inezakhiwo ezinamandla ze-paramagnetic.
Ukuthola amakhompiyutha angasetshenziswa njengezengezo zezinto ezintsha ze-ferromagnetic; IHolmium iodide esetshenziselwe ukukhiqizwa kwamalambu we-metal halide - amalambu e-holmium
Isicelo
. Njengamanje, ukusetshenziswa okuyinhloko kungukungafani noMhlaba i-Iodide, ekhipha imibala ehlukahlukene yokubuka ngesikhathi sokuphuma kwegesi. Into esebenzayo esetshenziswe kumalambu e-Holmium yi-Holmium iodide, engafinyelela ukugxila okuphezulu kwama-athomu wensimbi endaweni ye-arc, kuthuthukisa kakhulu ukusebenza kahle kwemisebe.
(2) IHolmium ingasetshenziswa njengesengezo se-ytttrium iron noma i-yttrium aluminium garnet.
. Ngakho-ke lapho usebenzisa i-HO Ugongolo lwamahhala olukhiqizwe amakristalu e-Holmium angasusa amafutha ngaphandle kokukhiqiza ukushisa ngokweqile, ngaleyo ndlela anciphise ukulimala okushisayo kwezicubu ezinempilo. Kubikwa ukuthi ukwelashwa kwe-holmium laser kwe-glaucoma e-United States kunganciphisa izinhlungu zeziguli ezihlinzwa. China 2 μ Izinga le-M Laser Crystals lifinyelele ezingeni lomhlaba wonke, futhi kufanele zenziwe imizamo yokuthuthukisa nokukhiqiza lolu hlobo lwe-Laser Crystal.

(6) I-Holmium Laser LithoToTipsy Technology: I-Meech Holmium Laser Lithodripsy ilungele amatshe ezinso ezinzima, amatshe ama-ureteral, namatshe e-bladder angeke aphulwe yi-extracorporporopeal shock wave lithodripsy. Lapho usebenzisa i-Holmium Laser Lithodripsy, i-fiber emfushane ye-Medical Holmium Laser isetshenziselwa ukufinyelela ngqo kwi-bladder, i-ureter, namatshe ezinso nge-urethra ne-uretoscope. Ngemuva kwalokho, ochwepheshe be-Urology basebenzisa iHolmium Laser ukuphula amatshe. Inzuzo yale ndlela yokwelashwa ye-holmium laser iwukuthi ingaxazulula amatshe ama-Ureteral, amatshe amnyama, kanye namatshe amaningi ezinso. Okubi yilokho kwamatshe athile asezingeni eliphezulu nangaphansi, kungahle kube nenani elincane lamatshe asele ngenxa yokungakwazi kwe-holmium laser fiber engena esizeni samatshe.
