Boron nitride CAS 10043-11-5
Boron nitride ndi kristalo wopangidwa ndi maatomu a nayitrogeni ndi ma atomu a boron. Kapangidwe ka kristalo kumagawidwa kukhala hexagonal boron nitride (HBN), yodzaza ndi hexagonal boron nitride (WBN) ndi kiyubiki boron nitride. Maonekedwe a kristalo a hexagonal boron nitride ali ndi mawonekedwe ofanana ndi ma graphite, omwe amawoneka otayirira, opaka mafuta, otulutsa chinyezi, ufa woyera wopepuka, motero amatchedwanso "white graphite". Kukula kokwanira kwa hexagonal boron nitride ndikofanana ndi quartz, koma matenthedwe amatenthedwe kuwirikiza kakhumi kuposa quartz. Imakhalanso ndi mafuta abwino pa kutentha kwakukulu ndipo ndi mafuta abwino kwambiri otentha kwambiri omwe amatha kuyamwa ndi neutroni, katundu wokhazikika wa mankhwala, ndi kusakhazikika kwa mankhwala pafupifupi pafupifupi zitsulo zonse zosungunuka. Hexagonal boron nitride sisungunuka m'madzi ozizira. Madzi akawiritsidwa, amasungunuka pang'onopang'ono ndikupanga boric acid ndi ammonia pang'ono. Sichichita ndi ma asidi ofooka ndi maziko amphamvu kutentha kutentha. Amasungunuka pang'ono mu asidi otentha ndipo amatha kuwola pothandizidwa ndi sodium hydroxide yosungunuka ndi potaziyamu hydroxide. Lili ndi dzimbiri kukana zosiyanasiyana inorganic zidulo, alkalis, mchere zothetsera ndi organic solvents.

1. Boron nitride imagwiritsidwa ntchito popanga zida zodzitchinjiriza, zida zotchinjiriza ng'anjo, komanso ntchito zamagetsi, makina, ndege ndi mafakitale ena.
2. Boron nitride ili ndi zinthu zambiri zabwino kwambiri ndipo imagwiritsidwa ntchito kwambiri m'ma insulators amagetsi othamanga kwambiri komanso othamanga kwambiri komanso ma arcs a plasma, zokutira zowotcherera zokha mafelemu osamva kutentha kwambiri, zida zopangira ng'anjo zapang'onopang'ono, zowonjezera gawo lolimba la ma semiconductors. , zida zomangira zopangira ma atomiki, zida zonyamula kuti zisawononge ma radiation ya neutroni, mawindo osinthira radar, media ya radar antenna ndi zida za injini ya rocket. Chifukwa cha mafuta ake abwino kwambiri, amagwiritsidwa ntchito ngati mafuta otenthetsera kwambiri komanso chowongolera pamitundu yosiyanasiyana. Boron nitride wopangidwa amatha kugwiritsidwa ntchito kupanga ma crucibles osagwirizana ndi kutentha kwambiri ndi zinthu zina. Itha kugwiritsidwa ntchito ngati zinthu zolimba kwambiri, zoyenera kufufuza za geological, zobowola mafuta ndi zida zodula kwambiri. Angagwiritsidwenso ntchito ngati zitsulo processing akupera zakuthupi, ndi makhalidwe a otsika processing pamwamba kutentha ndi zochepa padziko zilema za zigawo zikuluzikulu. Boron nitride itha kugwiritsidwanso ntchito ngati chowonjezera pazinthu zosiyanasiyana. Ulusi wa Boron nitride wopangidwa kuchokera ku boron nitride ndi sing'anga-modulus ulusi wogwira ntchito kwambiri. Ndizinthu zopangira uinjiniya zomwe zitha kugwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, mafakitale opanga nsalu, ukadaulo wazamlengalenga ndi magawo ena otsogola.
3.Release wothandizira zitsulo kupanga ndi lubricant kwa kujambula zitsulo waya; zipangizo zapadera za electrolytic ndi kukana pansi pa kutentha kwakukulu; mafuta olimba; kutentha chisindikizo desiccant kwa transistors ndi zowonjezera kwa ma polima monga pulasitiki resins; mankhwala boron nitride mbamuikha mu akalumikidzidwa zosiyanasiyana angagwiritsidwe ntchito monga kutentha, kuthamanga kwambiri, kutchinjiriza ndi kutentha dissipation zigawo zikuluzikulu; zipangizo zotetezera kutentha m'makampani opanga ndege; ndi kutenga nawo gawo kwa zothandizira, zimatha kusinthidwa kukhala kiyubiki boron nitride molimba ngati diamondi pambuyo pa kutentha kwambiri komanso chithandizo champhamvu kwambiri.
