A na-akpọ Boron Nitride, ihe eji eme boron. Hexagonal boron nitride bụ ụdị boron. Ndị nchọpụta enyochala mmetụta BN nanotubes na mkpụrụ ndụ osteoblastic mmadụ. Ndị nchọpụta chọpụtara na BNNT kpalitere ma na-abawanye uto osteoblast.

Hexagonal boron nitride

Boron nitride, kemịkalụ na thermally na-eguzogide ọgwụ, bụ ihe na-emegharị ahụ nke nwere usoro kemịkalụ BN. Ọ dị n'ụdị kristal dị iche iche, ọ bụkwa isoelectronic na lattice carbon. A na-eji ya na ngwa dị iche iche, gụnyere seramiiki, iko, na seramiiki mejupụtara.

Nitridation na-eme ya nke boric oxide na ammonolysis. Ọ nwere ihe ndị yiri ya na diamond. A na-ejikwa ya na ngwa abrasive, dị ka na pensụl ụzọ, na dị ka mmanu maka ciment.

Hexagonal boron Nitride abụghị ihe enwere ike iji maka nchekwa ike. Otú ọ dị, ọ nwere ezigbo nkwụsi ike na kemịkalụ inertness, nke na-eme ka ọ bụrụ onye na-adọrọ mmasị maka ngwa ndị dị otú ahụ. Ọ dịkwa mma na gburugburu ebe obibi, na-eme ka ọ na-adọrọ mmasị maka ngwa ike ndụ ndụ. Otú ọ dị, e nwere caveats ole na ole.

Boron nitride nwere oghere ike nke naanị 4 eV, na-eme ka ọ bụrụ ezigbo mkpuchi.

Ndị na-eme nchọpụta na-amụ ihe nwere akụkụ abụọ. Nke a gụnyere boron nitride hexagonal. Ihe a nwere ihe mkpuchi eletrik pụrụ iche, ezigbo mmanu mmanu, nguzogide corrosion na nkwụsi ike kemịkal. Oghere band nke hexagonal oyi akwa boron nitride buru ibu, na-eme ka ọ na-agbanwe agbanwe ma baa uru maka ọtụtụ ngwa.

Ngwa ahụ nwere kemịkalụ dị mma na nkwụsi ike ọkụ. Enwere ike iji ya na akụrụngwa okpomọkụ dị elu na nkedo ígwè. A pụkwara ịchọta ya n'ihe dị iche iche dị ka mmanụ mmanu, alloys, plastics, ma ọ bụ ihe ndị na-emepụta ihe. Ọ bụkwa akụkụ bara uru nke arịa mmeghachi omume na crucibles.

Hexagonal Boron Nitride bụ onye na-ekwe nkwa maka imepụta ihe akụkụ abụọ. Ọ nwere ọmarịcha ngwa anya, ike igwe, yana nkwụsi ike nke kemịkalụ na thermal. Dị ka graphene, hexagonal boron nitride ga-esi na ihe ndị na-ebu ụzọ mepụta ya.

Na mgbakwunye na ngwa semiconductor, boron nitride hexagonal nwere ike iji beryllium, sọlfọ, na carbon mee ihe. Ọ bụ nnukwu mkpụrụ maka graphene n'ihi oghere ya sara mbara yana ndenye refractive dị elu.

Hexagonal boron-nitride nwekwara ndabere ntụzịaka. A makwaara dị ka anisotropy, ndabere ntụziaka na-akọwa otú njirimara nke ihe si dị iche dị ka ụgbọ elu crystallographic nke ihe ahụ si dị.
