ʻO Boron Nitride kahi mea hana seramika holomua i loaʻa i ka ʻano paʻa a me ka pauka.ʻO kāna mau waiwai kūʻokoʻa - mai ka mana wela kiʻekiʻe a me ka conductivity thermal koʻikoʻi i ka machinability maʻalahi, ka lubricity, ka haʻahaʻa dielectric mau a me ka ikaika dielectric kiʻekiʻe - e hana i ka boron nitride i mea waiwai maoli.
Ma kona ʻano paʻa, kapa pinepine ʻia ka boron nitride ma ke ʻano he "graphite keʻokeʻo" no ka mea he microstructure e like me ka graphite.Eia nō naʻe, ʻaʻole like me ka graphite, ʻo ka boron nitride he insulator uila maikaʻi loa i ʻoi aku ka kiʻekiʻe o ka wela o ka oxidation.Hāʻawi ia i ka conductivity thermal kiʻekiʻe a me ke kūpaʻa haʻalulu wela maikaʻi a hiki ke maʻalahi i ka mīkini e pani i nā ʻae ʻana i nā ʻano like ʻole.Ma hope o ka mīkini ʻana, ua mākaukau no ka hoʻohana ʻana me ka ʻole o ka mālama ʻana i ka wela a i ʻole ke kī ʻana.
I loko o ka inert a me ka hoʻohaʻahaʻa ʻana i ka lewa, ʻo ka pae AX05 o nā māka Boron Nitride e kū i nā mahana ma luna o 2,000°C.Hoʻohana maʻamau ia ma ke ʻano he insulator e pili ana me ka tungsten a me nā electrodes graphite i kēlā mau wela.
Hiki ke hoʻohana ʻia nā māka Boron Nitride a pau i ka hoʻoheheʻe ʻana i ka lewa a hiki i 750°C.ʻAʻole pulu ia e ka hapa nui o nā metala i hoʻoheheʻe ʻia a me nā slags a hiki ke hoʻohana ʻia me ka nui o nā metala i hoʻoheheʻe ʻia e like me ka aluminika, sodium, lithium, silikon, boron, tin, germanium, a me ke keleawe.
Na Waiwai Nui Boron Nitride
No ka hana ʻana i nā ʻano paʻa, paʻi 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 mea paʻa a maʻalahi i ka mīkini a mākaukau e hoʻohana.Loaʻa ia ma kahi kokoke i nā ʻano maʻamau i hiki ke mīkini ʻia a loaʻa iā ia nā hiʻohiʻona kūʻokoʻa a me nā waiwai kino e waiwai ai ia no ka hoʻoponopono ʻana i nā pilikia paʻakikī i ka nui o nā noi ʻoihana.
