Ntlha ea pele,heliumke ntho ea lik'hemik'hale e nang le nomoro ea 2 ea athomo, e fokolang haholo, e se nang 'mala, e sa nkheng ebile e sa chese.Heliume sebelisoa haholo-holo ho pholisa, ho futhumatsa, sefofane, tlhahiso ea semiconductor, tlhahlobo ea khase le likarolo tse ling, 'me e sebelisoa haholo lipatlisisong tsa saense le tlhahiso ea indasteri.

Mabapi le mohloli oa khase, o tloaelehilengheliumhaholo-holo e tsoa hoheliumkhase ea tlhaho, e fumanoang ka ho arohana le ho hloekisa.Heliumhaholo-holo e teng libakeng tse ka tlas'a lefatše tsa oli le khase le mehloling ea metsi a ka tlas'a lefatše. Karolo ea eona e kholo kehelium-4 isotope, e nang le litaba tse ka bang 0.0005% ea khase. Tloaelehilengheliumkhase e kena ts'ebetsong ea tlhoekiso ea indasteri ho tlosa mongobo, oksijene, naetrojene, litšila, joalo-joalo, 'me joale e tloaelehileng.heliumkhase e nang le bohloeki bo phahameng e ka fumanoa.

Bohloeki bo phahamengheliume na le bohloeki bo phahameng, hangata bo bua ka bohloeki bo fetang 99.999% ("robong" tse hlano tsa bohloeki). Bohloeki bo phahamengheliume sebelisoa haholo lipatlisisong tsa mahlale le tlhahiso ea indasteri, joalo ka nyutlelie magnetic resonance, superconducting makenete, lasers, tlhahiso ea semiconductor le likarolo tse ling. Bohloeki bo phahamengheliumka kakaretso e ba le mekhoa e meng e metle ea karohano le tlhoekiso ho tlosa litšila tse ngata le ho laola likarohano tsa isotopu ho kopana.heliumlitlhoko tsa bohloeki mafapheng a khethehileng.

Ea bobeli, mabapi le bohloeki, bohloeki bo phahamengheliumhangata e hloekile hofeta tloaelohelium. Bohloeki hangata bo lekanyetsoa ka litekanyetso tse kang "li robong tse hlano" (99.999%), "lirobong tse tšeletseng" (99.9999%), le "li robong tse supileng" (99.99999%). Tlhokahalo e phahameng ea bohloeki bakeng sa bohloeki bo phahamengheliumke hobane mafapheng a mang a ts'ebeliso, joalo ka tlhahiso ea semiconductor le nuclear magnetic resonance, esita le boteng ba litšila tsa mohlala bo ka ba le phello e kholo ts'ebetsong ea sehlahisoa le liphetho tsa liteko.

Ea boraro, bohloeki bo phahamengheliumle tse tlwaelehilengheliumli boetse li fapane libakeng tsa kopo. Tloaelehilengheliume sebelisoa haholo-holo ho tjheseletsa e tloaelehileng, ho itšeha ka laser, ductile iron gase e sirelelitsoeng theknoloji ea welding le masimo a mang. Makaleng ana, litlhoko tsa bohloeki bakeng saheliumdi batla di le tlase, mme di tlwaelehileheliume se e ka fihlela litlhoko tse ngata. Bohloeki bo phahamengheliume sebelisoa mafapheng a mang a theknoloji e phahameng, joalo ka tlhahiso ea fiber ea optical, lipatlisiso tsa mahlale tsa superconducting, lipatlisiso tsa matla a nyutlelie, tlhahiso ea semiconductor, joalo-joalo.

Ho phaella ho bohloeki le masimo a kopo, bohloeki bo phahamengheliumle tse tlwaelehilengheliume boetse e fapane ka litšobotsi tsa ts'ebetso. Bohloeki bo phahamengheliume na le litšobotsi tsa lik'hemik'hale tse tsitsitseng, conductivity e ntle ea mocheso le boima bo tlaase. Ho tsitsa ha eona ka lik'hemik'hale ho etsa hore ho be thata bakeng sa bohloeki bo phahamengheliumho itšoara ka lik'hemik'hale le lintho tse ling, kahoo ho netefatsa botsitso le botšepehi ba eona litekong le mekhoa ea tlhahiso ea indasteri. Ka nako e ts'oanang, conductivity ea mocheso oa bohloeki bo phahamengheliume boetse e ntle haholo, e feta hole ea moea, e leng se etsang hore e be le litebello tse pharaletseng tsa ts'ebeliso ea lisebelisoa tsa sehatsetsi, tlhahiso ea semiconductor, boenjiniere ba nyutlelie le mafapha a mang. Ho phaella moo, molemo o tlaase oa segokanyipalo oa bohloeki bo phahamengheliume boetse e etsa hore e bapale karolo ea ho hlapolla metsoakong ea khase, e ka fokotsang ka nepo sekhahla le ho hanyetsa mokelikeli oa khase e tsoakiloeng.
