| Ndi chiyaniLanthanum Hexaboridekugwiritsidwa ntchito? Lanthanum Borideamapeza ntchito zambiri, zomwe zimagwira ntchito bwino pama radar system muzamlengalenga, mafakitale apamagetsi, zida, zitsulo zapanyumba, chitetezo cha chilengedwe komanso pafupifupi makumi awiri ankhondo ndiukadaulo wapamwamba kwambiri. LaB6amapeza ntchito zambiri m'makampani opanga ma elekitironi, omwe ali ndi katundu wabwinoko kuposa tungsten (W) ndi zinthu zina. Ndi abwino zakuthupi mkulu mphamvu pakompyuta umuna cathode. Imagwira ntchito pamtengo wokhazikika komanso wapamwamba kwambiri wa ma elekitironi, mwachitsanzo kujambula kwa electron beam, gwero la kutentha kwa ma elekitironi, mfuti yowotcherera ya ma elekitironi. Monocrystal lanthanum boride ndi yabwino kwambiri ya cathode yamachubu amphamvu kwambiri, chipangizo chowongolera maginito, mtengo wa elekitironi ndi accelerator. Lanthanum Hexaboridema nanoparticles amagwiritsidwa ntchito ngati kristalo limodzi kapena ngati zokutira pama cathodes otentha. Zipangizo ndi njira zomwe ma cathode a hexaboride amagwiritsidwa ntchito ndi monga ma electron microscopes, machubu a microwave, electron lithography, electron beam welding, X-ray chubu, ndi ma electron lasers aulere. LaB6imagwiritsidwanso ntchito ngati muyeso wa kukula / kupsinjika mu X-ray powder diffraction kuti athe kuwongolera kufalikira kwa nsonga za diffraction. LaB6ndi thermo electronic emitter ndi superconductor yokhala ndi kusintha kochepa |
