Boron nitride yog ib qho siv lead ua los ntawm cov nitrogen atoms thiab boron atoms. Cov qauv siv lead ua muab faib ua: hexagonal boron nitride (HBN), close-packed hexagonal boron nitride (WBN) thiab cubic boron nitride. Ntawm lawv, cov siv lead ua ntawm hexagonal boron nitride Cov qauv muaj cov qauv txheej zoo ib yam li graphite, qhia txog xoob, lubricating, noo noo-nqus, thiab lub teeb-hnyav hmoov dawb, yog li nws tseem hu ua "graphite dawb". Qhov ceev theoretical yog 2.27g / cm3, qhov hnyav tshwj xeeb yog 2.43, thiab Mohs hardness yog 2.
Hexagonal boron nitride muaj kev rwb thaiv hluav taws xob zoo, thermal conductivity.chemical stability, tsis muaj qhov pom tseeb melting point, 3000 ° C hauv 0.1MPA nitrogen, nyob rau hauv ib qho chaw txo qis, tiv taus cua sov rau 2000 ° C, siv hauv nitrogen thiab argon qhov kub tuaj yeem ncav cuag 2800 ° C, qhov ruaj khov tsis zoo hauv cov pa oxygen, thiab qhov kub siv qis dua 1000 ° C. Lub coefficient nthuav dav ntawm hexagonal boron nitride yog sib npaug rau cov quartz, tab sis lub thermal conductivity yog kaum npaug ntawm quartz. Nws kuj muaj lubricity zoo ntawm qhov kub siab. Nws yog ib qho roj nplua nyeem khoom kub zoo heev nrog lub peev xwm nqus neutron muaj zog, cov khoom tshuaj ruaj khov, thiab tshuaj lom neeg inert rau yuav luag txhua cov hlau yaj.
Hexagonal boron nitride tsis yaj hauv dej txias. Thaum dej npau, nws hydrolyzes qeeb heev thiab tsim tawm me ntsis boric acid thiab ammonia. Nws tsis cuam tshuam nrog cov kua qaub tsis muaj zog thiab cov hauv paus muaj zog ntawm chav tsev kub. Nws yaj me ntsis hauv cov kua qaub kub. Siv cov sodium hydroxide molten thiab potassium hydroxide. Kev ua tiav tuaj yeem decomposed. Nws muaj kev tiv thaiv corrosion ntau rau ntau yam inorganic acids, alkalis, ntsev daws thiab cov organic solvents.
