"Abafana abanzima" kwiintsimbi ezinqabileyo

Kwintsapho yentsimbi enqabileyo, kukho amalungu amaninzi "anobuntu obunenkani".Abanayo nje indawo ephezulu yokunyibilika, kodwa banokuxhathisa okuqinileyo kwe-corrosion kwaye abakhuphi lula emoyeni, ngoko babizwa ngokuba "abafana abanzima" kwiintsimbi.

Indawo yokunyibilika kwei-tungsteniphezulu njenge-3410 ° C, eyona iphakamileyo kuzo zonke iintsimbi, ngoko inokusetyenziswa njengempahla ye-filament.Ukumelana nokushisa okuphezulu kwe-2000 ° C yiqhekeza lekhekhe le-tungsten.I-Metal tungsten isetyenziswa kakhulu kwi-carbide ene-cemented, intsimbi ekhethekileyo kunye nezinye iimveliso, kwaye isetyenziswa ngokubanzi kwishishini lokukhusela, i-aerospace, imboni yolwazi, kwaye abanye abantu bayinika isihloko esithi "izinyo loshishino".

Indawo yesibini yokunyibilika yintsimbi yerhenium, eyi-3180 ℃.Kufanelekile ukukhankanya ukuba i-rhenium yinto enqabileyo ngokwenene.Umxholo wayo kwi-crust yomhlaba unqabile kakhulu kwaye uhlakazekile, kuphela phezulu kunezo zeprotactinium kunye neradium.Ngoko ke, yinto yokugqibela efunyenwe kwindalo.Ekubeni uMendeleev wafumanisa umthetho wexesha lezinto, izazinzulu aziphumelelanga ukuyifumana ngaphezu kwesiqingatha senkulungwane de yafunyanwa ngamachiza aseJamani ngo-1925.

Indawo yesithathu yokunyibilika yintsimbi ye-osmium, eyi-3045 ℃.Ngelo xesha, iphinda ibe yintsimbi enzima kakhulu kwindalo, kunye nokuxinana ukuya kwi-22.4 g / cm3.Kwindawo yesine kukho i-metal tantalum, enendawo yokunyibilika eyi-2996°C.

Iintsimbi ezinendawo yokunyibilika ngaphezu kwe-2000 ° C, kunye ne-molybdenum, i-hafnium, njl.Molybdenumyinto ebalulekileyo yokulandela abantu, izilwanyana kunye nezityalo.Isixa esipheleleyo se-molybdenum equlethwe kumzimba womntu omdala ngu-9 mg, kunye nomxholo ophezulu kwisibindi kunye nezintso.Izityalo ziyakwazi ukulungisa i-nitrogen phantsi kwesenzo se-molybdenum kwaye iguqule i-nitrogen ibe yifom enokuthi ifunxe.I-Molybdenum isetyenziselwa ukusulungekisa iintsimbi ezahlukeneyo zealloy, iintsimbi ezingenasici, iintsimbi ezikwaziyo ukumelana nobushushu kunye ne-alloys ephezulu.Isetyenziswa kakhulu kwishishini lomkhosi kwaye yaziwa ngokuba "yintsimbi yemfazwe".Indawo yokunyibilika kwesinyithihafniumyi2233°C.Kufanelekile ukukhankanya ukuba i-alloy ye-hafnium, i-Ta4fC5, yinto eneyona ndawo iphezulu yokunyibilika eyaziwayo, malunga ne-4215 ° C.
