Ma ke kahua o nā mea holomua, ke ʻimi mau nei nā mea noiʻi i nā palena hou i ka ʻimi ʻana i nā mea me nā waiwai kūikawā e hiki ke hoʻololi i nā ʻoihana like ʻole. ʻO kekahi o ia mau mea kupaianaha ʻo ia ka hexagonal boron nitride (h-BN). I kapa pinepine ʻia ʻo "mea kupanaha," ke loaʻa nei ka hexagonal boron nitride i ka ikaika ma ke ʻano he mea hana maʻalahi me nā ʻano noi like ʻole. E ʻeli hohonu kākou i loko o ke ao o ka hexagonal boron nitride a e ʻimi i kona mau waiwai kūikawā a me ka hiki ke hoihoi.
He aha ka hexagonal boron nitride?
ʻO ka hexagonal boron nitride kahi hui i haku ʻia me nā ʻāpana like o nā ʻātoma boron a me ka nitrogen i hoʻonohonoho ʻia i loko o kahi ʻano hexagonal lattice. Ua like kona ʻano me ka graphite, akā ʻokoʻa loa kona mau waiwai mai nā mea i hoʻokumu ʻia i ke kalapona.
Ka hoʻokele wela maikaʻi loa:
ʻO kekahi o nā waiwai koʻikoʻi o h-BN ʻo ia kona conductivity thermal kiʻekiʻe. Hiki i ka hexagonal boron nitride ke hoʻokele pono i ka wela me ka mālama ʻana i ka insulation uila. ʻO kēia waiwai ka mea waiwai nui i nā ʻoihana e like me ka aerospace, nā mea uila a me ka hoʻokele thermal.
Ma ka ʻoihana uila, ʻenekini boron hexagonalua hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe wela kūpono loa i hiki ke hoʻokuʻu i ka wela i hana ʻia e nā mea uila liʻiliʻi. ʻO ka conductivity thermal maikaʻi loa o ka mea e hōʻoiaʻiʻo ana i nā ʻāpana uila e noho anuanu, no laila e hoʻonui ai i kā lākou hana a me ke ola lōʻihi.
Lubrication a me ka uhi ʻana:
Hōʻike pū ka hexagonal boron nitride i nā waiwai lubrication maikaʻi loa. He haʻahaʻa kona coefficient o ka friction, e lilo ia i lubricant maloʻo maikaʻi loa. Ua loaʻa i kēia hiʻohiʻona nā noi ma nā ʻoihana he nui, me ke kaʻa, ka aerospace a me ka hana ʻana.
Eia kekahi, hoʻohana nui ʻia ʻo h-BN ma ke ʻano he uhi anti-stick i nā noi e pili ana i nā kaʻina hana wela kiʻekiʻe. ʻO ka hiki o ka mea ke kū i nā mahana koʻikoʻi me ka ʻole o ka pane ʻana me nā mea ʻē aʻe e kūpono ai no nā uhi ʻana ma nā ipu hoʻoheheʻe, nā ʻōmole, a me nā lako ʻē aʻe i hoʻohana ʻia i ka hoʻolei metala a me ka hana aniani.
Nā Waiwai Dielectric a me nā Uila:
Ma muli o kona hiki ke hoʻokaʻawale i ka uila, h-BNua loaʻa nā noi i nā mea uila. ʻO kona kūpaʻa kiʻekiʻe i ke au uila e hiki ai ke hana i nā mea hoʻokaʻawale hilinaʻi a me nā mea hoʻokele wela. Hāʻawi kēia i nā manawa kūpono no ka hoʻomohala ʻana i nā mea uila kūpono a paʻa e like me nā transistors mana kiʻekiʻe a me nā kaapuni i hoʻohui ʻia.
ʻO ke kūlana kiʻekiʻe o ka substrate:
ʻO ka nitride boron hexagonalhoʻohana pinepine ʻia ma ke ʻano he substrate i nā kaʻina hana ulu like ʻole. Hāʻawi kona ʻano kristal i kahi kumu kūpono no ka ulu ʻana o ka 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 hoʻomākaukau i ke ala no nā noi uila a me nā optoelectronic hou.
i ka hopena:
Me nā waiwai maikaʻi loa e like me ka conductivity thermal, nā hiki lubrication, nā hiki dielectric a me nā waiwai substrate kiʻekiʻe, loaʻa i ka hexagonal boron nitride ka hiki ke nui i nā ʻoihana like ʻole. Ke hoʻomau nei nā mea noiʻi e ʻimi a aʻo e pili ana i kēia mea kupaianaha, hiki ke loaʻa nā noi hoihoi hou aʻe i ka wā e hiki mai ana.
Mai ka hoʻokele wela a me ka lubrication i ka hana ʻana a hiki i nā mea uila i hoʻonui ʻia a me nā substrates ulu kiʻekiʻe, hāʻawi ka hexagonal boron nitride i nā hiki he nui no ka hoʻomaikaʻi ʻana i nā ʻenehana e kū nei a me ka hiki ʻana i nā hoʻonā hou. I ka wā e apo ai ka honua i nā mea hoʻomau a holomua, e pāʻani ka hexagonal boron nitride i kahi kuleana koʻikoʻi i ke ʻano o ka wā e hiki mai ana.
