Hexagonal Boron Nitride: He Mea Kupanaha Nui

Ma ke kahua o nā mea holomua, ke ʻimi mau nei nā mea noiʻi i nā palena hou no ka ʻimi ʻana i nā mea me nā waiwai kūʻokoʻa hiki ke hoʻololi i nā ʻoihana like ʻole. ʻO kekahi o ia mea kupaianaha he hexagonal boron nitride (h-BN). ʻO ka manawa pinepine i kapa ʻia ʻo "mea kupanaha," hexagonal boron nitride ka loaʻa ʻana o ka manawa ma ke ʻano he mea maʻalahi me ka nui o nā noi. E ʻimi hohonu kākou i ka honua o ka boron nitride hexagonal a e ʻimi i kona mau waiwai kūʻokoʻa a me nā mea hoihoi.

 He aha ka boron nitride hexagonal? 

Hexagonal boron nitride he pūhui i haku ʻia me nā ʻāpana like o ka boron a me nā ʻātoma nitrogen i hoʻonohonoho ʻia i loko o kahi ʻano lattice hexagonal. Ua like ia me ka graphite, akā ʻokoʻa loa kona mau waiwai mai nā mea kalapona.

 ʻOi aku ka maikaʻi o ka thermal conductivity: 

ʻO kekahi o nā mea kaulana loa o ka h-BN ʻo ia kona conductivity thermal kiʻekiʻe. Hiki i ka Hexagonal boron nitride ke alakaʻi maikaʻi i ka wela me ka mālama ʻana i ka insulation uila. He waiwai nui kēia waiwai i nā ʻoihana e like me ka aerospace, electronics a me ka hoʻokele wela.

I ka ʻoihana uila,hexagonal boron nitride ua hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe wela maikaʻi loa i hiki ke hoʻopau i ka wela i hana ʻia e nā mea uila paʻa. ʻO ka maikaʻi maikaʻi o ka thermal conductivity e hōʻoia i nā mea uila e noho mālie, a laila e hoʻonui ai i kā lākou hana a me ka lōʻihi.

 Lubrication a me ka uhi: 

Hexagonal boron nitride hōʻike pū i nā waiwai lubrication maikaʻi loa. He haʻahaʻa haʻahaʻa ia o ka friction, e hoʻolilo iā ia i lubricant maloʻo maikaʻi loa. Ua loaʻa kēia hiʻohiʻona i nā noi i nā ʻoihana he nui, me ka automotive, aerospace a me ka hana ʻana.

Eia kekahi, hoʻohana nui ʻia ka h-BN ma ke ʻano he anti-stick coating i nā noi e pili ana i nā kaʻina hana kiʻekiʻe. ʻO ka hiki i ka mea ke kū i nā wela wela me ka ʻole o ka hoʻopili ʻana me nā mea ʻē aʻe he mea kūpono ia no ka uhi ʻana i nā crucibles, mold, a me nā mea hana ʻē aʻe i hoʻohana ʻia i ka hoʻolei metala a me ka hana aniani.

 Nā waiwai dielectric a me nā mea uila: 

Ma muli o kona hiki ke hoʻokaʻawale uila,h-BN ua loaʻa nā noi ma ka uila. ʻO kona kūpaʻa kiʻekiʻe i ke au uila hiki ke hana i nā insulators hilinaʻi a me ka thermally conductive. Hāʻawi kēia i nā manawa kūpono no ka hoʻomohala ʻana i nā mea uila uila kūpono e like me nā transistors kiʻekiʻe a me nā kaapuni hoʻohui.

 ʻO ka substrate kūlana kiʻekiʻe: 

 Hexagonal boron nitride hoʻohana pinepine ʻia ma ke ʻano he substrate i nā ʻano hana ulu. Hāʻawi kona ʻano aniani i kumu kūpono no ka ulu epitaxial o nā mea ʻē aʻe, me ka graphene a me nā mea ʻelua-dimensional ʻē aʻe. Hoʻomaikaʻi kēia i ka maikaʻi o ka mea a hāʻawi i ke ala no nā noi uila a me optoelectronic hou.

i ka hopena:

Me nā waiwai maikaʻi e like me ka thermal conductivity, ka lubrication hiki, dielectric a me nā waiwai substrate kiʻekiʻe, hexagonal boron nitride he nui ka mana ma nā ʻano ʻoihana. Ke hoʻomau nei ka poʻe noiʻi e ʻimi a aʻo e pili ana i kēia mea kupanaha, loaʻa paha i nā noi hoihoi hou aku i ka wā e hiki mai ana.

Mai ka hoʻokele wela a me ka lubrication i ka hana ʻana i nā mea uila i hoʻonui ʻia a me nā substrates ulu kiʻekiʻe, hāʻawi ʻo hexagonal boron nitride i nā mea hiki ke helu ʻia no ka hoʻomaikaʻi ʻana i nā ʻenehana i kēia manawa a hiki i nā hopena hou. I ka hoʻopili ʻana o ka honua i nā mea hoʻomau a me ka holomua, hexagonal boron nitride e hana koʻikoʻi i ka hana ʻana i ka wā e hiki mai ana.
