ʻO Boron Nitride kahi mea seramika synthetic holomua i loaʻa i ke ʻano paʻa a me ka pauka. ʻO kona mau waiwai kūikawā - mai ka mana wela kiʻekiʻe a me ka conductivity thermal koʻikoʻi a hiki i ka machinability maʻalahi, lubricity, dielectric constant haʻahaʻa a me ka ikaika dielectric kiʻekiʻe - e hoʻolilo i ka boron nitride i mea kūikawā maoli.
Ma kona ʻano paʻa, ua kapa pinepine ʻia ʻo boron nitride he "graphite keʻokeʻo" no ka mea he microstructure like kona me ko graphite. Eia nō naʻe, ʻaʻole like me ka graphite, he insulator uila maikaʻi loa ka boron nitride nona ka mahana oxidation kiʻekiʻe. Hāʻawi ia i ka conductivity thermal kiʻekiʻe a me ke kūpaʻa haʻalulu thermal maikaʻi a hiki ke maʻalahi ke mīkini ʻia e pani i nā tolerances ma aneane kekahi ʻano. Ma hope o ka mīkini ʻana, ua mākaukau no ka hoʻohana ʻana me ka ʻole o ka mālama wela a i ʻole nā hana puhi.
I loko o nā lewa inert a me nā lewa hoʻemi, e kū ka papa AX05 o nā papa Boron Nitride i nā mahana ma luna o 2,000°C. Hoʻohana pinepine ʻia ia ma ke ʻano he insulator i ka wā e pili ana me nā electrodes tungsten a me graphite ma kēlā mau mahana.
Hiki ke hoʻohana ʻia nā papa Boron Nitride āpau i nā lewa oxidizing a hiki i 750°C. ʻAʻole ia e pulu ʻia e ka hapa nui o nā metala hoʻoheheʻe ʻia a me nā slags a hiki ke hoʻohana ʻia i ka launa pū ʻana me ka hapa nui o nā metala hoʻoheheʻe ʻia e like me ka alumini, sodium, lithium, silicon, boron, tin, germanium, a me ke keleawe.
Nā Waiwai Boron Nitride Nui
No ka hana ʻana i nā ʻano paʻa, ua kaomi wela ʻia nā pauka BN a me nā mea hoʻopaʻa i loko o nā bila a hiki i 490mm x 490mm x 410mm ma nā kaomi a hiki i 2000 psi a me nā mahana a hiki i 2000°C. Hoʻokumu kēia kaʻina hana i kahi mea i mānoanoa a maʻalahi ke mīkini ʻia a mākaukau e hoʻohana. Loaʻa ia ma kahi o kēlā me kēia ʻano maʻamau i hiki ke mīkini ʻia a he mau ʻano kūikawā a me nā waiwai kino e lilo ai ia i mea waiwai no ka hoʻoponopono ʻana i nā pilikia paʻakikī ma nā ʻano hana ʻoihana like ʻole.
