Boron Nitride, nke a makwaara dị ka BN, Hexagonal Boron Nitride (H-BN), na Boron Nitride na-ekpo ọkụ, bụ seramiiki mmanye onwe ya nke ọma nke nwere ike iguzogide okpomọkụ dị elu ma nọgide na-enwe ike mmanye ya na gburugburu oghere dị elu.A na-eme crucibles boron nitride nke AEM site na boron nitride oghere na-ekpo ọkụ.Hexagonal Boron Nitride (H-BN) na-eme omume n'otu aka ahụ na graphite mechanically mana ọ na-enye ezigbo nguzogide eletriki., enwere ike imepụta ya dị ka ngwaahịa ikpeazụ BN dị ka crucible, ụgbọ mmiri, mkpuchi, wdg.
Isi atụmatụ
Boron nitride nwere ezigbo mkpuchi ọkụ, nrụpụta ọkụ, nkwụsi ike kemịkalụ, na enweghị ebe mgbaze doro anya.Oke ojiji okpomọkụ na 0.1MPA nitrogen nwere ike iru 3000 Celsius C, na a na-anọpụ iche mbenata ikuku, ọ nwere ike idi okpomọkụ ruo 2000 Celsius C, na ojiji okpomọkụ na nitrogen na argon nwere ike iru 2800 Celsius C, na nkwụsi ike na ikuku oxygen bụ. adịghị mma, na ojiji okpomọkụ dị n'okpuru 1000 Celsius.Ọnụọgụ mgbasawanye nke boron nitride hexagonal bụ nke quartz, mana ikuku ọkụ ji okpukpu iri karịa nke quartz.
Tụkwasị na nke ahụ, boron nitride hexagonal anaghị agbaze na mmiri oyi, na mgbe a na-esi mmiri ahụ, hydrolysis na-adị ngwa ngwa ma na-emepụta obere boric acid na amonia.Ọ naghị emeghachi omume na acid na-adịghị ike na ntọala siri ike na ụlọ okpomọkụ, ọ na-agbaze ntakịrị na acid dị ọkụ, ọ dịkwa mkpa ka a gwọọ ya na sodium hydroxide gbazere na potassium hydroxide ka ire ere.
