Noi:
LanthanumHoʻohana nui ʻia ka hana hexaboride i ka ʻoihana electron, ʻoi aku ka maikaʻi o kāna waiwai hoʻokuʻu ʻia ma mua o nā mea ʻē aʻe e like me W a hoʻohana nui ʻia i ka microscope electron, etc. haʻahaʻa loa (e pili ana i 1K). E like me ka lanthanum hexaboride poisoning he nui nā hana maikaʻi loa, no ka laʻana, ka ikaika o ka hoʻokuʻu ʻana o ka electron, ka pale ʻana i ka radiation ikaika, ke kūpaʻa kemika maikaʻi i ka wela wela, etc. Hiki ke hoʻohana ʻia i ka radar, aerospace, ʻoihana uila, nā mea kani, nā mea lapaʻau, nā mea pono hale, ka ʻoihana metallurgy, etc.ʻO ia, ʻo ka lanthanum boride hoʻokahi kristal ka mea maikaʻi loa e hana ai i ka valve mana kiʻekiʻe, magnetron, electron beam, ion beam, accelerator cathode.
