Boron nitride CAS 10043-11-5
Boron nitride bụ kristal mejupụtara atom nitrogen na atọm boron. E kewara usoro kristal ahụ ka ọ bụrụ hexagonal boron nitride (HBN), boron nitride hexagonal hexagonal (WBN) juru na ya na cubic boron nitride. Ọdịdị kristal nke hexagonal boron nitride nwere ụdị graphite layered Ọdịdị, na-egosi rụrụ arụ, lubricated, mmiri na-amịkọrọ, ìhè ọcha ntụ ntụ, ya mere a na-akpọ ya "ọcha graphite". Ọnụọgụ mgbasawanye nke boron nitride hexagonal bụ otu quartz, mana ikuku ọkụ ji okpukpu iri karịa nke quartz. Ọ nwekwara ezigbo mmanu na oke okpomọkụ ma bụrụ ezigbo mmanu siri ike na-ekpo ọkụ nke nwere ikike nnabata neutron siri ike, akụrụngwa kemịkalụ kwụsiri ike, yana inert kemịkalụ na ihe fọrọ nke nta ka ọ bụrụ ọla niile a wụrụ awụ. Hexagonal boron nitride bụ ihe a na-apụghị ịsacha na mmiri oyi. Mgbe esichara mmiri, ọ na-eji nwayọọ nwayọọ na-amịpụta obere boric acid na amonia. Ọ naghị emeghachi omume na acid adịghị ike na ntọala siri ike na ụlọ okpomọkụ. Ọ na-agbaze ntakịrị na acid na-ekpo ọkụ ma enwere ike ree ya naanị site n'ịgwọ ya na sodium hydroxide gbazere na potassium hydroxide. Ọ nwere nnukwu nguzogide corrosion dị iche iche inorganic acid, alkalis, ngwọta nnu na ihe mgbaze organic.
