SUOYI Boron Nitride Powder BN hexagonal boron nitride HBN CBN RBN WBN

Boron nitride bụ kristal mejupụtara atom nitrogen na atọm boron. E kewara ihe owuwu kristal ahụ ka ọ bụrụ hexagonal boron nitride (HBN), nnukwu boron nitride hexagonal (WBN) juru na cubic boron nitride. Ọdịdị kristal nke hexagonal boron nitride nwere ụdị graphite yiri nke ahụ, na-egosi rụrụ arụ, mmanye, nnabata mmiri dị mfe, ịdị arọ dị arọ na ihe odide ndị ọzọ nke ntụ ntụ ọcha, ya mere a na-akpọkwa ya "ọcha graphite".

Usoro njupụta 2.27g/cm3, ike ndọda pụrụ iche: 2.43, Mo hardness bụ 2.

Hexagonal boron nitriding nwere ezigbo mkpuchi eletriki, conductivity thermal, kemịkalụ nkwụsi ike, enweghị ebe mgbaze doro anya, nguzogide okpomọkụ na 0.1MPA nitrogen ruo 3000ºC, na-ebelata ikuku na-anọpụ iche, iguzogide okpomọkụ na 2000ºC, nitrogen na argon na ojiji nke okpomọkụ nwere ike iru 2800ºC, na ikuku oxygen kwụsie ike adịghị mma, ojiji nke okpomọkụ n'okpuru 1000ºC.

Hexagonal boron nitride nwere otu ọnụọgụ mgbasawanye dị ka quartz, mana ikuku ọkụ ya ji okpukpu iri karịa nke quartz. Ọ nwekwara ezigbo mmanu na oke okpomọkụ, ọ bụ ezigbo mmanu mmiri siri ike dị elu, nwere ikike nnabata neutron siri ike, nkwụsi ike kemịkalụ, yana kemịkalụ na-abanye n'ihe fọrọ nke nta ka ọ bụrụ ọla niile gbazere.

Hexagonal boron nitride bụ ụdị ihe seramiiki dị elu. Ihe microstructure ya na-agba agba na usoro ihe omimi ya bụ kristal hexagonal. Hexagonal boron nitride nwere ihe pụrụ iche ma mara mma nke anụ ahụ na kemịkal. Ọ nwere ezigbo conductivity thermal, mkpuchi eletrik, nguzogide corrosion kemịkalụ na nguzogide oxidation. Ọ nwere ike idi ihe ruru 1000OC na ikuku, yana ruo 2000OC na gas inert na oghere. A na-agbanye kristal boron nitride n'ogo dị elu nke 2000OC, nwere kemịkalụ siri ike na nke anụ ahụ yana ezigbo ihe na-eme ka ọkụ dị mma (nchịkọta okpomọkụ nke otu kristal bụ ihe dịka 250-300W / mk).
