Idan aka kwatanta da tungsten cathodes,lanthanum hexaborate (LaB6) cathodes suna da fa'idodi irin su ƙarancin aikin tserewa na lantarki, haɓakar iska mai yawa, juriya ga fashewar ion, juriya mai kyau na guba, aikin barga, da tsawon rayuwar sabis. An yi nasarar yin amfani da shi a cikin manyan kayan aiki da kayan aiki daban-daban kamar su tushen plasma, binciken microscopy na lantarki, na'urorin lithography na lantarki, Auger spectroscopy, da na'urorin lantarki. Asalin dukiya naLaB6, LaB6, nasa ne na nau'in CsCI nau'in cubic primitive lattice. Zarra na Lanthanum sun mamaye kusurwoyi takwas na cube. Kwayoyin zarra guda shida na boron suna samar da octahedron kuma suna tsakiyar kubu. An kafa haɗin haɗin gwiwa tsakanin BB, kuma rashin isassun electrons yayin haɗin kai tsakanin BB ana samar da su ta hanyar zarra na lanthanum. La yana da valence electron lamba na 3, kuma kawai 2 electrons ake bukata don shiga cikin bonding. Sauran 1 electron ya zama electron kyauta. Don haka, haɗin La-B haɗin ƙarfe ne mai ƙarfi mai ƙarfi da haɓaka mai kyau. Saboda haɗin kai tsakanin ƙwayoyin halittar B, ƙarfin haɗin gwiwa yana da girma, ƙarfin haɗin gwiwa yana da ƙarfi, kuma tsayin haɗin gajere ne, yana haifar da ƙaramin tsari na LaB6. Yana da wasu halaye kamar babban taurin, babban wurin narkewa, da juriya kusa daƙananan ƙarfe na duniya.
