Boron Nitride ndi chinthu chapamwamba chopangidwa ndi ceramic chomwe chimapezeka mu mawonekedwe olimba komanso a ufa. Makhalidwe ake apadera - kuyambira kutentha kwambiri komanso kutentha kwambiri mpaka makina osavuta kugwiritsa ntchito, mafuta, kusinthasintha kwa dielectric komanso mphamvu yapamwamba ya dielectric - zimapangitsa boron nitride kukhala chinthu chabwino kwambiri.
Mu mawonekedwe ake olimba, boron nitride nthawi zambiri imatchedwa "graphite yoyera" chifukwa ili ndi kapangidwe kakang'ono kofanana ndi ka graphite. Komabe, mosiyana ndi graphite, boron nitride ndi chotetezera magetsi chabwino kwambiri chomwe chili ndi kutentha kwakukulu kwa okosijeni. Chimapereka kutentha kwakukulu komanso kukana kutentha kwambiri ndipo chimatha kupangidwa mosavuta kuti chitseke kulekerera kulikonse. Pambuyo pokonza, imakhala yokonzeka kugwiritsidwa ntchito popanda ntchito zina zowonjezera zochizira kutentha kapena kuwombera.
Mu mpweya wopanda mpweya komanso wocheperako, mtundu wa AX05 wa mtundu wa Boron Nitride umapirira kutentha kopitilira 2,000°C. Nthawi zambiri umagwiritsidwa ntchito ngati chotetezera kutentha chomwe chimakhudzana ndi ma electrode a tungsten ndi graphite pa kutentha kumeneko.
Mitundu yonse ya Boron Nitride ingagwiritsidwe ntchito m'mlengalenga wothira okosijeni mpaka 750°C. Sinyowa ndi zitsulo zambiri zosungunuka ndi zotsalira ndipo ingagwiritsidwe ntchito pokhudzana ndi zitsulo zambiri zosungunuka kuphatikizapo aluminiyamu, sodium, lithiamu, silicon, boron, tin, germanium, ndi mkuwa.
Katundu Wathunthu wa Boron Nitride
Kuti apange mawonekedwe olimba, ufa wa BN ndi zomangira zimatenthedwa m'ma billets mpaka 490mm x 490mm x 410mm pa kutentha mpaka 2000 psi ndi kutentha mpaka 2000°C. Njirayi imapanga zinthu zokhuthala komanso zosavuta kupangidwa komanso zokonzeka kugwiritsidwa ntchito. Zimapezeka pafupifupi mu mawonekedwe aliwonse omwe angapangidwe ndipo zili ndi mawonekedwe apadera komanso zinthu zakuthupi zomwe zimapangitsa kuti zikhale zothandiza kuthetsa mavuto ovuta m'mafakitale osiyanasiyana.
