Boron nitrideis sophisticated synthetic ceramic inouya muhupfu uye yakasimba fomu.Boron nitridechinhu chakasarudzika chechokwadi nekuda kwehunhu hwayo hwakakosha, hunosanganisira kupisa kwakanyanya, kusarudzika kupisa conductivity, kuve nyore kwemachining, lubricity, yakaderera dielectric kugara, uye yakawedzera dielectric simba.
Boron nitrideinowanzonzi "white graphite" muchimiro chayo chakasimba nekuda kweiyo microstructure yayo yakafanana negraphite. Nekudaro, kusiyana negraphite, boron nitride iri nani insulator yemagetsi ine tembiricha yakakura yeoxidation. Iyo ine yakasimba yekupisa conductivity uye yekupisa kutyisa kuramba uye inogona kugadzirwa kuti ivhare kushivirira munenge chero chimiro. Yakagadzirira kushandiswa mushure mekugadzira uye haidi chero yekuwedzera kupisa kurapwa kana moto maitiro.
Zvakanakira:
Excellent machinability
Low density
High kupisa conductivity
High magetsi resistivity
Yakanaka makemikari inertness
Yakanakisa thermal shock resistance
Corrosion-resistant
Nowetting
Low dielectric constant (k=4)
Anisotropic (thermal conductivity inosiyana pakati peparallel uye perpendicular ndege kune inotsikirira nzira).
High-tembiricha zvinhu
Dielectric breakdown simba>40 KV/mm
40 KV/mm
Applications:
1. High-Temperature Metallurgy uye Semiconductor:
Evaporation Boats: Inoshandiswa kune vacuum aluminium film deposition, chinhu chakakosha mubhizinesi rekurongedza (semuenzaniso, mabhegi ekurongedza chikafu).
Midziyo yekunyungudutsa simbi inosanganisira macrucibles, pombi, uye nozzles yekuburitsa aluminium yakanyungudutswa, pamwe nevanogovera uye zvikamu zvevharuvhu zvekunyungudutsa-kuchena simbi kana semiconductors.
Horizontal Inoenderera Kukandira Kuparadzanisa Rings: Ita shuwa kudzikamisa kwakatsetseka uye kupera kwepamusoro panguva yekuramba ichikandwa simbi kana mhangura.
2. Electronics, Electrical Engineering, Thermal Management:
Heat Dissipation Substrates: Anoshandiswa mumaLED ane simba guru, radio frequency microwave devices, IGBT modules, uye mamwe maapplication kuwana chiyero chepamusoro chekuvharisa magetsi uye thermal conductivity.
High-voltage magetsi emagetsi anosanganisira yakakwirira-tembiricha insulators, plasma arc nozzles, uye yakakwirira-voltage switch accessories.
3. Muchadenga uye Dziviriro:
Radar Windows uye Radomes: Ratidza yakanakisa wave-pachena zvivakwa (zvakajeka kune microwaves) uye inogona kumira aerodynamic thermal shock, inoshandiswa mumakomba, radar, uye zvimwe midziyo.
High-Temperature Lubricant: Anoshandiswa mumabhengi, njanji, uye mamwe mamiriro akaomarara.
Processing Precautions:Nyangweboron nitride
inozivikanwa se "yakareruka machinable ceramic," zvinotevera zvibodzwa zvichiri kuda kutariswa panguva chaiyo yekugadzirisa:
Kusarudzwa kwechishandiso: High-speed steel kana carbide zvishandiso zvinokurudzirwa.
