Boron nitride CAS 10043-11-5
ʻO Boron nitride kahi aniani i haku ʻia me nā ʻātoma nitrogen a me nā ʻātoma boron. Hoʻokaʻawale ʻia ka ʻano aniani i loko o ka hexagonal boron nitride (HBN), hexagonal boron nitride (WBN) kokoke loa a me cubic boron nitride. ʻO ke ʻano aniani o ka hexagonal boron nitride he ʻano like like me ka graphite layered structure, e hōʻike ana i kahi wehe, lubricated, moisture-absorbing, māmā keʻokeʻo pauka, no laila ua kapa ʻia ʻo ia ʻo "white graphite". ʻO ka helu hoʻonui o ka hexagonal boron nitride ua like ia me ka quartz, akā ʻo ka conductivity thermal he ʻumi manawa o ka quartz. Loaʻa iā ia ka lubricity maikaʻi ma nā wela kiʻekiʻe a he lubricant paʻa kiʻekiʻe kiʻekiʻe me ka ikaika neutron absorption hiki, paʻa kemika waiwai, a me ka inertness kemika i nā metala hehee a pau. Hexagonal boron nitride ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai anuanu. Ke hoʻolapalapa ʻia ka wai, hydrolyzes me ka mālie a hoʻohua i kahi nui o ka wai boric a me ka amonia. ʻAʻole ia e hana me nā ʻakika nāwaliwali a me nā kumu ikaika ma ka lumi wela. Hiki ke hoʻoheheʻe ʻia i loko o ka ʻakika wela a hiki ke hoʻoheheʻe ʻia me ka hoʻoheheʻe ʻana me ka sodium hydroxide a me ka potassium hydroxide. Loaʻa iā ia ke kūpaʻa corrosion i nā ʻakika inorganic like ʻole, alkalis, nā paʻakai paʻakai a me nā mea hoʻoheheʻe organik.

1. Hoʻohana ʻia ʻo Boron nitride e hana i nā mea refractory, nā mea hoʻoheheʻe umu ahi, a hoʻohana ʻia hoʻi i ka uila, nā mīkini, nā mokulele a me nā ʻoihana ʻē aʻe.
2. He nui nā waiwai maikaʻi o Boron nitride a hoʻohana nui ʻia i nā insulators no ka uila kiʻekiʻe a me ka uila kiʻekiʻe a me nā arcs plasma, nā uhi no ka hoʻoheheʻe ʻana i nā kiʻekiʻe kiʻekiʻe, nā mea no nā umu induction kiʻekiʻe. , nā mea hoʻolālā no nā mea hoʻoheheʻe atomic, nā mea hoʻopihapiha e pale ai i ka radiation neutron, nā puka makani hoʻololi radar, nā mea hoʻolaha antenna radar a me nā mea ʻenekini rocket. Ma muli o kāna mau mea lubricating maikaʻi loa, hoʻohana ʻia ia ma ke ʻano he lubricant wela kiʻekiʻe a me kahi demoulding agent no nā ʻano like ʻole. Hiki ke hoʻohana ʻia ka boron nitride e hana i nā crucibles kūpaʻa kiʻekiʻe a me nā huahana ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he mea paʻa loa, kūpono no ka ʻimi ʻana i ka honua, nā ʻāpana wili ʻaila a me nā mea hana ʻoki kiʻekiʻe. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe metala, me nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka liʻiliʻi o nā hemahema o nā ʻāpana. Hiki ke hoʻohana ʻia ʻo Boron nitride i mea hoʻohui no nā mea like ʻole. ʻO ka pulupulu Boron nitride i hana ʻia mai ka boron nitride he fiber-modulus high-functional fiber. He mea ʻenehana synthetic inorganic hiki ke hoʻohana nui ʻia i ka ʻoihana kemika, ʻoihana textile, ʻenehana aerospace a me nā ʻāpana ʻoihana ʻokiʻoki ʻē aʻe.
3. Hoʻokuʻu i luna no ka hana metala a me ka lubricant no ke kaha kiʻi uea metala; nā mea electrolytic kūikawā a me nā mea kū'ē ma lalo o ka wela kiʻekiʻe; lubricant paʻa; desiccant seal wela no nā transistors a me nā mea hoʻohui no nā polymers e like me nā resins plastik; Hiki ke hoʻohana ʻia nā huahana boron nitride i kaomi ʻia i nā ʻano like ʻole e like me ke kiʻekiʻe kiʻekiʻe, ke kaomi kiʻekiʻe, ka insulation a me nā ʻāpana hoʻopau wela; nā mea pale wela i ka ʻoihana aerospace; me ke komo ʻana o nā catalysts, hiki ke hoʻololi ʻia i cubic boron nitride e like me ka paʻakikī e like me ke daimana ma hope o ka wela kiʻekiʻe a me ka mālama ʻana i ke kaomi kiʻekiʻe.
25kgs / pahu a i ʻole i hoʻonohonoho ʻia e like me nā koi o ka mea kūʻai aku
