Zoumba za Boron Nitride (BN) zili m'gulu la zoumba zaluso kwambiri zaukadaulo. Amaphatikiza zinthu zosagwirizana ndi kutentha, monga matenthedwe apamwamba kwambiri, okhala ndi mphamvu ya dielectric yayikulu komanso kusagwira bwino ntchito kwamankhwala kuti athetse mavuto m'malo ena ofunikira kwambiri padziko lonse lapansi.

Magawo opangidwa ndi ceramic-filimu yopyapyala amatchedwanso zida za semiconductor. Zimapangidwa ndi zigawo zingapo zopyapyala zomwe zamangidwa pogwiritsa ntchito zokutira, kuyika, kapena njira zothirira. Mapepala agalasi okhala ndi makulidwe osakwana milimita imodzi omwe ali ndi mbali ziwiri (zosalala) kapena mawonekedwe atatu amaonedwa kuti ndi magawo a ceramic opyapyala. Zitha kupangidwa kuchokera ku v

Pomwe Si3N4 imaphatikiza ma conductivity abwino kwambiri amafuta ndi magwiridwe antchito amakina. Kutentha kwamafuta kumatha kufotokozedwa pa 90 W/mK, ndipo kulimba kwake ndikwapamwamba kwambiri pakati pa zoumba zofananira. Makhalidwewa akuwonetsa kuti Si3N4 iwonetsa kudalirika kwambiri ngati gawo lapansi lazitsulo.

Boron nitride ceramics ali ndi mphamvu yodabwitsa komanso magwiridwe antchito amafuta omwe amakhala okhazikika modabwitsa, kuwapangitsa kukhala abwino kupanga ma nozzles omwe amagwiritsidwa ntchito popanga zitsulo zosungunuka.

Boron Carbide (B4C) ndi ceramic yolimba yopangidwa ndi Boron ndi kaboni. Boron Carbide ndi imodzi mwazinthu zolimba kwambiri zomwe zimadziwika, zomwe zili pachitatu kuseri kwa ma cubic Boron nitride ndi diamondi. Ndi chinthu chogwirizana chomwe chimagwiritsidwa ntchito pazinthu zosiyanasiyana zofunika, kuphatikiza zida zankhondo, ma vests oteteza zipolopolo, ndi mafuta owononga injini. M'malo mwake, ndizomwe zimakondedwa pazogwiritsa ntchito zosiyanasiyana zamafakitale

High matenthedwe madutsidwe ndi otsika coefficient wa kukulitsa matenthedwe. Kuphatikizika kwazinthuku kumapereka kukana kwamphamvu kwamafuta, kupangitsa kuti zoumba za Silicon Carbide zikhale zothandiza m'mafakitale osiyanasiyana. Komanso ndi semiconductor ndipo mphamvu zake zamagetsi zimapangitsa kuti zikhale zoyenera pa ntchito zosiyanasiyana. Amadziwikanso chifukwa cha kuuma kwake kwambiri komanso kukana dzimbiri.

Aluminiyamu nitride imakhala ndi matenthedwe apamwamba kwambiri (170 W/mk, 200 W/mk, ndi 230 W/mk) komanso mphamvu yamphamvu ya dielectric.

Kutenthedwa kwa kutentha nthawi zambiri kumakhala chifukwa chachikulu cha kulephereka kwa ntchito zotentha kwambiri. Zimapangidwa ndi zigawo zitatu: kukula kwa matenthedwe, kusinthasintha kwa kutentha, ndi mphamvu. Kusintha kwa kutentha kwachangu, ponse paŵiri mmwamba ndi pansi, kumayambitsa kusiyana kwa kutentha mkati mwa gawolo, mofanana ndi kung’ambika kumene kumadza chifukwa cha kupaka ayezi pa galasi lotentha. Chifukwa cha kufalikira kosiyanasiyana ndi kutsika, kuyenda

Makampani opanga magalimoto akuyenda ndi luso pogwiritsa ntchito zida zapamwamba zaukadaulo kuti apange zosintha zomwe zikuyenda bwino pamapangidwe ake onse komanso zigawo zina zamagalimoto am'badwo watsopano.

Ma bearings ndi ma valve ndi awiri mwa omwe amagwiritsidwa ntchito kwambiri pamipira ya silicon nitride ceramic. Kupanga mipira ya silicon nitride kumagwiritsa ntchito njira yomwe imaphatikizira kukanikiza kwa isostatic ndi kuthamanga kwa gasi. Zida zopangira izi ndi silicon nitride ufa wabwino komanso zothandizira zoziziritsa kukhosi monga aluminium oxide ndi yttrium oxide.
