Ọdịdị kristal nke hexagonal boron nitride nwere usoro dị larịị nke yiri graphite, na-egosi rụrụ arụ, mmanye, dị mfe ịmịkọrọ mmiri, ịdị arọ dị arọ na ihe ndị ọzọ nke ntụ ntụ ọcha, ya mere a na-akpọ ya "ọcha graphite".Njupụta usoro iwu bụ 2.27g/cm³, ike ndọda a kapịrị ọnụ bụ 2.43, na ike Mohs bụ 2.
Hexagonal boron nitride nwere uru nke enweghị abrasion, mma mmanu mmanu, ọkụ ọkụ na nhazi dị mfe n'ihe gbasara akụrụngwa.
N'ihe gbasara njirimara eletriki, ọ nwere uru nke ike dielectric dị mma, obere dielectric na-adịgide adịgide, obere ọnwụ na nnukwu ugboro, ntinye ngwa ndakwa nri, na mkpuchi ọkụ eletrik dị mma.
Hexagonal boron nitride nwere uru nke njikwa okpomọkụ dị elu, ikike okpomọkụ dị elu, mgbasawanye ọkụ dị ala, nkwụsị ọkụ ọkụ, oke ọkụ ọkụ na nchekwa okpomọkụ dị elu n'ihe gbasara njirimara ọkụ.
N'ihe gbasara akụrụngwa kemịkalụ, ọ nwere uru nke nkwụsi ike nke kemịkalụ, nguzogide corrosion, nguzogide oxidation, wetting dị ala, na enweghị ịrapara.
Ultra-mma boron nitride ntụ ntụ nwere ike iji na mkpuchi.Ihe mkpuchi boron nitride bụ ihe inert inorganic na-ekpo ọkụ na-ekpo ọkụ.Ọ naghị akwado ma ọ bụ banye n'ime ọla a wụrụ awụ.Ọ nwere ike ichekwa ihe mkpuchi nke na-ejikọta ya na aluminum gbazere, magnesium, zinc alloy na slag a wụrụ awụ ma ọ bụ n'elu arịa seramiiki na-agbatị ndụ arịa dị otú ahụ.
Uru nke boron nitride eji na mkpuchi:
Enweghị mmetọ na gburugburu ebe obibi, ọ dịghị mmerụ ahụ n'ahụ mmadụ.Na-adịghị egbu egbu, enweghị isi pụrụ iche.Enweghị ihe egwu nke mgbawa ma ọ bụ mgbawa.
Ezi okpomọkụ na-eguzogide, ruo 400 ~ 1700 ℃.Ọrụ mgbochi corrosion na ogologo ndụ ọrụ.Ghọta ọgwụgwọ onwe gị na okpomọkụ ụlọ.Na-eguzogide ịka nká na radieshon.Ezigbo nguzogide mmiri, nguzogide ịgba nnu, na ihe mgbaze organic.
Ihe mkpuchi ahụ nwere ike njikọ siri ike na mkpụrụ.Ihe mkpuchi ahụ nwere ike siri ike, iguzogide esemokwu na mmetụta.
