Lanthanum Hexaboride

Lus piav qhia luv luv:

Lanthanum Hexaboride (LaB 6,kuj hu ua lanthanum boride thiab LaB) yog ib qho tshuaj inorganic, boride ntawm lanthanum.Raws li cov khoom siv refractory ceramic uas muaj qhov melting point ntawm 2210 ° C, Lanthanum Boride yog insoluble hauv dej thiab hydrochloric acid, thiab hloov mus rau oxide thaum rhuab (calcined).Cov qauv Stoichiometric yog xim liab-violet, thaum cov boron nplua nuj (saum LaB6.07) yog xiav.Lanthanum Hexaboride(LaB6) paub txog nws qhov hardness, mechanical zog, thermionic emission, thiab muaj zog plasmonic zog.Tsis ntev los no, cov txheej txheem tshiab nruab nrab-kub hluavtaws tau tsim los ncaj qha rau kev sib txuas ntawm LaB6 nanoparticles.

Dab tsi yogLanthanum Hexaboridesiv rau?

Lanthanum Boridetau txais kev siv dav, uas ua tiav siv rau radar system hauv aerospace, hluav taws xob kev lag luam, ntsuas, khoom siv hauv tsev metallurgy, kev tiv thaiv ib puag ncig thiab txog nees nkaum tub rog thiab kev lag luam siab.

LaB 6tau txais kev siv ntau hauv kev lag luam hluav taws xob, uas muaj cov khoom siv hluav taws xob zoo dua li tungsten (W) thiab lwm yam khoom siv.Nws yog cov khoom siv zoo tshaj plaws rau lub zog hluav taws xob hluav taws xob emission cathode.

Nws ua lub luag haujlwm hauv kev ruaj khov thiab siab lub neej electron beam, piv txwv li electron beam engraving, electron beam heat source, electron beam welding gun.Monocrystal lanthanum boride yog cov khoom siv cathode zoo tshaj plaws rau lub zog siab lub raj, cov khoom siv sib nqus, cov nqaj hlau hluav taws xob thiab cov accelerator.

Lanthanum Hexaboridenanoparticles yog siv los ua ib qho siv lead ua los yog txheej rau kub cathodes.Cov cuab yeej siv thiab cov txheej txheem uas siv cov hexaboride cathodes suav nrog electron microscopes, microwave tubes, electron lithography, electron beam welding, X-ray tubes, thiab dawb electron lasers.

LaB 6Nws kuj tseem siv los ua tus qauv loj / lim hauv X-ray hmoov diffraction los ntsuas ntsuas ntsuas qhov dav ntawm diffraction peaks.

LaB 6yog ib qho thermo electronic emitter thiab superconductor nrog kev hloov pauv qis
