I-Lanthanum Hexaboride

Incazelo emfushane:

I-Lanthanum Hexaboride (LaB6,ebizwa nangokuthi i-lanthanum boride kanye ne-LaB) iyikhemikhali ye-inorganic, i-boride ye-lanthanum. Njengempahla ye-ceramic ephikisayo enephuzu lokuncibilika elingu-2210 °C, i-Lanthanum Boride ayincibiliki kakhulu emanzini ne-hydrochloric acid, futhi iguqulela ku-oxide lapho ishiswa (i-calcined). Amasampula e-Stoichiometric anombala onsomi-violet, kuyilapho acebile nge-boron (ngaphezulu kwe-LaB6.07) aluhlaza okwesibhakabhaka.I-Lanthanum Hexaboride(LaB6) yaziwa ngobulukhuni bayo, amandla emishini, ukukhishwa kwe-thermionic, kanye nezakhiwo eziqinile ze-plasmonic. Muva nje, kusungulwe indlela entsha yokwenziwa kwezinga lokushisa elimaphakathi ukuze kuhlanganiswe ngokuqondile ama-nanoparticles e-LaB6.

YiniI-Lanthanum Hexaborideusetshenziselwe?

I-Lanthanum Borideithola izinhlelo zokusebenza ezibanzi, ezisebenza ngempumelelo kusistimu ye-radar ku-aerospace, imboni ye-elekthronikhi, insimbi, insimbi yasendlini, ukuvikelwa kwemvelo kanye nemboni yezempi kanye nezobuchwepheshe obuphezulu cishe amashumi amabili.

LaB6ithola ukusetshenziswa okuningi embonini ye-electron, ephethe impahla engcono yokukhipha insimu kune-tungsten(W) nezinye izinto. Kuyinto impahla ekahle amandla aphezulu electronic emission cathode.

Idlala indima ekuzinzeni okuphezulu nasekuphileni okuphezulu kwe-electron ugongolo, isibonelo ukuqoshwa kwe-electron beam, umthombo wokushisa we-electron beam, isibhamu sokushisela i-electron beam. I-Monocrystal lanthanum boride iyindlela engcono kakhulu ye-cathode yeshubhu yamandla aphezulu, idivayisi yokulawula kazibuthe, i-electron beam ne-accelerator.

I-Lanthanum Hexaborideama-nanoparticles asetshenziswa njengekristalu eyodwa noma njenge-coating kuma-cathodes ashisayo. Amadivayisi namasu okusetshenziswa kuwo ama-cathode e-hexaboride ahlanganisa ama-electron microscopes, amashubhu e-microwave, i-electron lithography, i-electron beam welding, amashubhu e-X-ray, namalaser e-electron amahhala.

LaB6iphinda isetshenziswe njengendinganiso yosayizi/ubunzima ku-X-ray powder diffraction ukuze kulinganiswe ukunwetshwa kwensimbi kweziqongo ze-diffraction.

LaB6i-thermo electronic emitter kanye ne-superconductor enenguquko ephansi uma kuqhathaniswa
