Boron nitride CAS 10043-11-5
Boron nitride kristal ne wanda ya ƙunshi atom ɗin nitrogen da zarra na boron. An raba tsarin crystal zuwa boron nitride hexagonal hexagonal (HBN), na kusa da cubic boron nitride (WBN) da boron nitride cubic. Tsarin lu'ulu'u na boron nitride hexagonal yana da nau'in nau'in zane mai launi iri ɗaya, yana gabatar da sako-sako, mai mai, mai shayarwa, farin foda mai haske, don haka ana kiransa "farar graphite". Ƙimar faɗaɗa na boron nitride mai hexagonal daidai yake da ma'adini, amma yanayin zafi ya ninka na ma'adini sau goma. Hakanan yana da mai mai kyau a yanayin zafi mai kyau kuma yana da kyakkyawan madaidaicin mai mai zafi mai ƙarfi mai ƙarfi tare da ƙarfin shanyewar neutron, bargarin sinadarai, da rashin kuzarin sinadarai zuwa kusan duk narkakken karafa. Hexagonal boron nitride ba ya narkewa a cikin ruwan sanyi. Lokacin da aka tafasa ruwa, yana yin ruwa a hankali a hankali kuma yana samar da ɗan ƙaramin boric acid da ammonia. Ba ya amsawa tare da raunin acid da tushe mai ƙarfi a cikin zafin jiki. Yana da ɗan narkewa a cikin acid mai zafi kuma za'a iya rushe shi ta hanyar jiyya da narkakken sodium hydroxide da potassium hydroxide. Ya na da babba lalata juriya ga daban-daban inorganic acid, alkalis, gishiri mafita da Organic kaushi.
