Isicelo:
Umsebenzi we-Lanthanum hexaboride usetshenziswa kakhulu embonini yama-electron, impahla yayo yokukhipha insimu ingcono kunezinye izinto ezifana ne-W futhi isetshenziswa kabanzi kusibonakhulu se-electron, njll. izinga lokushisa liphansi kakhulu (cishe ngo-1K).Njengoba ubuthi be-lanthanum hexaboride busebenza kahle kakhulu, isibonelo, ukushuba kwe-electron emission enamandla, ukumelana nemisebe eqinile, ukuzinza okuhle kwamakhemikhali ekushiseni okuphezulu, njll.Le nto isetshenziswa kabanzi kwezempi kanye nobuchwepheshe obuphezulu obuningi. izindawo.Ingasetshenziswa ku-radar, i-aerospace, imboni ye-elekthronikhi, izinsimbi, izinsiza zezokwelapha, izinto zasendlini, imboni ye-metallurgy, njll.Okukhona, i-lanthanum boride single crystal iyinto engcono kakhulu yokwenza i-valve enamandla amakhulu, i-magnetron, i-electron beam, i-ion beam, i-accelerator cathode.
