Lanthanum hexaborate cathode yoherezamo ibikoresho

Ugereranije na Cathodes yo Kwishura,Lanthanum hexarate (Labol) cathodes have advantages such as low electron escape work, high emission electron density, resistance to ion bombardment, good poisoning resistance, stable performance, and long service life. Byakoreshejwe neza mubikoresho bitandukanye byihariye nibikoresho nkibisimba bya plasma, gusikana microscopy, electron beam imashini za Lithography, aumer, aumer, na electron. Umutungo shingiro yaLabol, Labol, ni iy CSCI andika Cubic ya mbere. Lanthanum atome ifite impande umunani za cube. Atome esheshatu za atome zigize octahedron kandi ziherereye hagati ya cube. Umuryango uringanijwe ufitwe hagati ya BB, na electle idahagije mugihe cyo guhuza BB itangwa na Lanthanam Atome. LA ifite agaciro ka electron ya 3, kandi harakenewe electron 2 gusa irakenewe kugirango yitabe ishami. Electron 1 isigaye ihinduka electron yubusa. Kubwibyo, Bond ya La-B ni intungamubiri nicyuma gifite imyitwarire myinshi cyane kandi ifite ubuzima bwiza. Kubera amavuta ya covory hagati ya B atome, imbaraga zo kwambara ni ndende, imbaraga za vend zirakomeye, kandi uburebure bwabahwa ni bugufi, bikavamo imiterere yihariye ya laborak6. Ifite ibintu bimwe na bimwe bikomeye, ingingo yo gushonga cyane, no kurwanya hafiNtibisanzwe Ibyuma Byisi.
