Daim ntawv thov

Cov khoom siv hlau nplaum: Holmium paub txog nws cov khoom sib nqus muaj zog thiab muaj txiaj ntsig zoo hauv kev tsim cov khoom siv hlau nplaum zoo. Holmium hlau nplaum yog siv nyob rau hauv ntau yam kev siv, nrog rau sib nqus refrigeration systems, qhov uas lawv pab ua kom tsis muaj kub los ntawm adiabatic demagnetization. Daim ntawv thov no yog ib qho tseem ceeb tshwj xeeb hauv cryogenics thiab txuag hluav taws xob cua txias tshuab.
Lasers: Holmium yog siv nyob rau hauv solid-state lasers, tshwj xeeb tshaj yog holmium-doped yttrium aluminium garnet (Ho:YAG) lasers. Cov lasers no tawm lub teeb ntawm lub wavelength ntawm 2100 nm, uas yog absorbed los ntawm dej, ua rau lawv zoo tagnrho rau kev kho mob daim ntawv thov xws li laser phais thiab lithotripsy (tawg lub raum pob zeb). Holmium lasers kuj tseem siv rau hauv cov ntawv thov kev lag luam rau kev txiav thiab vuam cov ntaub ntawv.
Nuclear Application: Holmium tuaj yeem siv rau hauv kev siv tshuab nuclear vim nws cov khoom siv neutron absorption. Holmium-166 yog radioactive isotope siv nyob rau hauv qee hom kev kho mob qog noj ntshav. Tsis tas li ntawd, holmium tuaj yeem siv rau hauv kev tswj rods ntawm nuclear reactors los pab tswj cov txheej txheem fission thiab txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm kev tsim hluav taws xob nuclear.
Alloying tus neeg sawv cev: Holmium yog siv los ua tus neeg sawv cev alloying rau ntau yam hlau los txhim kho lawv cov khoom siv dag zog thiab kev tiv thaiv corrosion. Nws feem ntau ntxiv rau npib tsib xee thiab lwm yam tsis tshua muaj lub ntiaj teb alloys kom lawv lub zog thiab thermal stability. Cov holmium-muaj alloys no yog siv nyob rau hauv aerospace, electronics, thiab lwm yam kev ua tau zoo daim ntawv thov uas muaj kev ntseeg siab yog ib qho tseem ceeb.
