ʻO Boron Nitride Crucible BN Crucible
Aʻo Huahana
ʻO Boron Nitride, i ʻike ʻia ʻo BN, Hexagonal Boron Nitride (H-BN), a me Boron Nitride i hoʻopaʻa ʻia i ka wela, he seramika hoʻomaʻemaʻe ponoʻī maikaʻi loa e hiki ke kū i nā wela kiʻekiʻe a mālama i kona hiki ke hoʻomaʻamaʻa ʻia i loko o kahi ʻenekini kiʻekiʻe.Hana ʻia nā kīʻaha Boron Nitride o AEM mai ka pahu wela boron nitride blank.Hana like ʻo Hexagonal Boron Nitride (H-BN) me ka graphite mechanically akā hāʻawi i ke kūpaʻa uila maikaʻi loa., a hiki ke hana ʻia e like me nā huahana hope BN e like me ka crucible, waʻa, uhi, etc.
Nā hiʻohiʻona nui
Loaʻa i ka Boron nitride ka insulation uila maikaʻi, conductivity thermal, kūpaʻa kemika, ʻaʻohe wahi heheʻe.ʻO ka mahana hoʻohana kiʻekiʻe loa i ka 0.1MPA nitrogen hiki ke hiki i 3000 ° C, i kahi ea hoʻohaʻahaʻa kūʻokoʻa, hiki iā ia ke kū i ka wela a 2000 ° C, a hiki i ka mahana hoʻohana i ka nitrogen a me ka argon hiki ke hiki i 2800 ° C, a ʻo ke kūpaʻa i ka lewa oxygen. ʻilihune, a ʻo ka mahana hoʻohana ma lalo o 1000 °C.Ua like ka huina hoonui o ka hexagonal boron nitride me ka quartz, aka, o ka hoonui wela he umi manawa ia o ka quartz.
Eia kekahi, ʻaʻole e hoʻoheheʻe ʻia ka boron nitride hexagonal i ka wai anuanu, a i ka wā i hoʻolapalapa ʻia ai ka wai, lohi loa ka hydrolysis a hoʻohua i kahi liʻiliʻi o ka boric acid a me ka amonia.ʻAʻole ia e hana me ka ʻakika nāwaliwali a me ke kumu ikaika ma ka lumi wela, hiki ke hoʻoheheʻe ʻia i loko o ka ʻakika wela, a pono e mālama ʻia me ka molten sodium hydroxide a me ka potassium hydroxide e decompose.

Hoʻohana Huahana
ʻO ka Boron nitride kahi ʻano o ka pale wela kiʻekiʻe, ke kūpaʻa corrosion, ka conductivity thermal kiʻekiʻe, ka insulation kiʻekiʻe a me ka hana lubrication maikaʻi loa o ka mea, ke kūlana o kēia manawa e hoʻomaʻamaʻa i ke kaʻina hana, hoʻemi i nā kumukūʻai hana, hoʻomaikaʻi i ke ola lawelawe o nā mea ʻoi aku ka ikaika o kēia manawa. kuhikuhi noiʻi o ia mau mea.
(1) Ke hoʻohana nei i ka paʻa kemika maikaʻi loa o ka hexagonal boron nitride, hiki ke hoʻohana ʻia e like me nā crucibles, nā moku, nā paipu hoʻopuka metala wai, nā nozzles rocket, nā kumu mana kiʻekiʻe, nā pipeline metala i hoʻoheheʻe ʻia, nā ʻāpana pāpaʻi, nā mea hoʻoheheʻe kila, etc. hoʻoheheʻe i nā metala i hoʻoheheʻe ʻia.
(2) Ke hoʻohana nei i ka wela a me ka corrosion kū'ē o ka hexagonal boron nitride, nā ʻāpana wela kiʻekiʻe, nā papa hoʻoheheʻe rocket, nā pale wela o ka mokulele, nā mea hana magnetocurrent, etc.
(3) Ke hoʻohana nei i ka insulation o ka hexagonal boron nitride, ua hoʻohana nui ʻia ia i ka uila kiʻekiʻe kiʻekiʻe kiʻekiʻe a me ka plasma arc insulators a me nā insulators o nā mea hoʻomehana like ʻole, nā puʻupuʻu hoʻomehana a me ka wela kiʻekiʻe, kiʻekiʻe-frequency, high-voltage insulation a ʻāpana hoʻoheheʻe wela, a me ka hoʻohana pinepine ʻana o nā mea umu uila.
