Boron nitrideʻO kahi keramic synthetic paʻakikī e hele mai i ka pauka a me ke ʻano paʻa.Boron nitrideHe mea ʻokoʻa maoli ia ma muli o kona mau ʻano kūikawā, ʻo ia ka nui o ka wela wela, ka maʻalahi o ka mīkini, ka lubricity, ka mau dielectric haʻahaʻa, a me ka ikaika dielectric i hoʻonui ʻia.

Boron nitrideʻike pinepine ʻia ʻo ia ʻo "white graphite" ma kona ʻano paʻa ma muli o kona microstructure like me ka graphite. Eia nō naʻe, ʻaʻole like me ka graphite, ʻoi aku ka maikaʻi o ka boron nitride i ka insulator uila me ka ʻoi aku ka nui o ka wela o ka hoʻonā. Loaʻa iā ia ka conductivity thermal ikaika a me ke kūpaʻa haʻalulu wela a hiki ke hana ʻia e pani i nā tolerances i kahi ʻano like ʻole. Mākaukau ia e hoʻohana ma hope o ka mīkini ʻana a ʻaʻole koi i ka mālama wela hou a i ʻole nā ​​​​kaʻina ahi.

Pono:

• Machinability maikaʻi loa

• haʻahaʻa haʻahaʻa

• Ka hoʻoili wela kiʻekiʻe

• Ke pale uila kiʻekiʻe

• ʻO ka inertness kemika maikaʻi

• Kūleʻa haʻalulu wela maikaʻi

• Paʻa ʻino

• ʻO ka pulu ʻole

• mau dielectric haʻahaʻa (k=4)

• Anisotropic (ʻokoʻa ka hoʻoili wela ma waena o nā mokulele kūlike a me ka pololei i ke kuhikuhi kaomi).

• Nā mea wela kiʻekiʻe

• ʻO ka ikaika hoʻohaʻahaʻa dielectric> 40 KV/mm

40 KV/mm

Nā noi:

• 1. Mea Metala Kiekie a me Semiconductor:

• Nā Waʻa Evaporation: Hoʻohana ʻia no ka waiho ʻana i nā kiʻiʻoniʻoni aluminika, kahi mea koʻikoʻi i ka ʻoihana ʻeke (e laʻa, nā ʻeke ʻeke meaʻai).

• Loaʻa nā lako hoʻoheheʻe metala i nā crucibles, nā paipu, a me nā nozzles no ka lawe ʻana i ka alumini hoʻoheheʻe ʻia, a me nā mea hoʻolaha a me nā ʻāpana valve no ka hoʻoheheʻe ʻana i nā metala maʻemaʻe kiʻekiʻe a i ʻole semiconductor.

Horizontal Continuous Casting Separation Rings: E hōʻoia i ka hoʻoheheʻe ʻana a me ka hoʻopau ʻana o ka ʻili i ka wā e hoʻolei mau ʻia ai ke kila a i ʻole ke keleawe.

• 2. Electronics, Electrical Engineering, Thermal Management:

• Heat Dissipation Substrates: Hoʻohana ʻia i nā LED mana kiʻekiʻe, nā mea uila uila uila, nā modula IGBT, a me nā noi ʻē aʻe e loaʻa ai ke koena maikaʻi loa o ka insulation uila a me ka conductivity thermal.

ʻO nā ʻāpana uila kiʻekiʻe e loaʻa nā insulators wela kiʻekiʻe, nā nozzles arc plasma, a me nā mea hoʻololi kiʻekiʻe-voltage.

• 3. Aerospace a me ka pale kaua:

• ʻO Radar Windows a me Radomes: Hōʻike i nā waiwai hawewe-alohi maikaʻi loa (ʻike i nā microwaves) a hiki ke kū i ka haʻalulu wela aerodynamic, i hoʻohana ʻia i nā missiles, radar, a me nā mea hana ʻē aʻe.

Nā Lubricants Kiʻekiʻe: Hoʻohana ʻia i nā bearings, alakaʻi alakaʻi, a me nā kūlana koʻikoʻi ʻē aʻe.

Hoʻoponopono i ka mālama ʻana:ʻOiaiboron nitride

• ʻike ʻia ʻo ia he "ceramic maʻalahi maʻalahi," pono e nānā ʻia nā mea i lalo i ka wā e hana maoli ai:

• Koho mea hana: Paipai ʻia nā mea kila kiʻekiʻe a i ʻole nā ​​mea hana carbide.
