| He aha kaLanthanum Hexaboridehoʻohana ʻia no ka? Lanthanum Borideloaʻa i nā noi ākea, e pili pono ana i ka ʻōnaehana radar i ka aerospace, ʻoihana uila, mea kani, metallurgy mea hana hale, palekana kaiapuni a ma kahi o iwakālua a me ka ʻoihana ʻenehana kiʻekiʻe. LaB6loaʻa i nā mea hoʻohana he nui i ka ʻoihana electron, nona ka waiwai hoʻokuʻu ʻoi aku ka maikaʻi ma mua o ka tungsten (W) a me nā mea ʻē aʻe. He mea kūpono ia no ka cathode hoʻokuʻu uila mana kiʻekiʻe. He hana koʻikoʻi ia ma ke ʻano paʻa a me ke ola kiʻekiʻe o ka uila uila, no ka laʻana, ke kahakaha ʻana i ka kukuna electron, ke kumu wela electron beam, ka pū wili uila uila. ʻO ka monocrystal lanthanum boride ka mea cathode maikaʻi loa no ka paipu mana kiʻekiʻe, ka mana mana magnetic, ka uila uila a me ka wikiwiki. Lanthanum Hexaboridehoʻohana ʻia nā nanoparticles ma ke ʻano he aniani hoʻokahi a i ʻole he uhi ma nā cathodes wela. ʻO nā mea hana a me nā ʻenehana e hoʻohana ʻia ai nā cathodes hexaboride me nā microscopes electron, nā paipu microwave, ka lithography electron, ka hoʻoheheʻe ʻana i ke kukui uila, nā paipu X-ray, a me nā laser electron manuahi. LaB6Hoʻohana ʻia ʻo ia ma ke ʻano he nui/strain standard i ka X-ray powder diffraction e calibrate instrumental broadening o diffraction peaks. LaB6He mea hoʻopuka uila thermo a me superconductor me kahi hoʻololi haʻahaʻa |
