I-Boron nitrideiyi-ceramic yokwenziwa eyinkimbinkimbi eza iyimpushana futhi iqinile.I-Boron nitrideiyinto ehlukile ngempela ngenxa yezimfanelo zayo ezikhethekile, ezihlanganisa amandla okushisa aphezulu, ukuguquguquka kwe-thermal okukhethekile, ukuba lula komshini, ukuthambisa, ukuguquguquka kwe-dielectric okuphansi, namandla athuthukisiwe e-dielectric.
I-Boron nitridengokuvamile ibizwa ngokuthi "i-graphite emhlophe" ngesimo sayo esiqinile ngenxa ye-microstructure yayo eqhathaniswa ne-graphite. Kodwa-ke, ngokungafani ne-graphite, i-boron nitride iyisivikeli esingcono sikagesi esinokushisa okukhulu kwe-oxidation. Ine-conductivity eqinile ye-thermal kanye nokumelana nokushaqeka okushisayo futhi ingenziwa ngomshini ukuvala ukubekezelelana cishe kunoma yikuphi ukuma. Ilungele ukusetshenziswa ngemva komshini futhi ayidingi ukwelashwa okwengeziwe kokushisa noma izinqubo zomlilo.
Izinzuzo:
Excellent machinability
Ukuminyana okuphansi
Ukushisa okuphezulu
High resistivity kagesi
Ukungabi namakhemikhali okuhle
Ukumelana nokushaqeka okuhle kakhulu kwe-thermal
Ukumelana nokubola
Ukungamanzisi
I-dielectric engaguquki ephansi (k=4)
I-Anisotropic (i-thermal conductivity iyahlukahluka phakathi kwezindiza ezihambisanayo ne-perpendicular kuya kusiqondiso esicindezelayo).
Izinto ezisezingeni eliphezulu
Amandla okuqhekeka kwe-Dielectric> 40 KV/mm
40 KV/mm
Izicelo:
1. I-High-Temperature Metallurgy ne-Semiconductor:
Izikebhe Zokuhwamuka: Isetshenziselwa ukufakwa kwefilimu ye-aluminum ye-vacuum, ingxenye ebalulekile ebhizinisini lokupakisha (isb., izikhwama zokupakisha ukudla).
Imishini yokuncibilikisa insimbi ihlanganisa iziphamba, amapayipi, namabhomu okuletha i-aluminium encibilikisiwe, kanye nabasabalalisi nezingxenye zamavalvu zokuncibilikisa izinsimbi ezihlanzekile kakhulu noma ama-semiconductors.
Amandandatho Okuhlukanisa Okusakaza Okuqhubekayo Avundlile: Qinisekisa ukubhidliza okushelelayo nokuqedwa kwendawo ngesikhathi sokusakazwa okuqhubekayo kwensimbi noma ithusi.
2. I-Electronics, Electrical Engineering, Thermal Management:
I-Heat Dissipation Substrates: Asetshenziswa kuma-LED anamandla amakhulu, kumadivayisi erediyo ye-microwave, amamojula e-IGBT, nezinye izinhlelo zokusebenza ukuze kuzuzwe ibhalansi engcono kakhulu yokufaka ugesi kanye ne-thermal conductivity.
Izingxenye zikagesi ezinama-voltage aphezulu zifaka ama-insulators ashisa kakhulu, ama-plasma arc nozzles, kanye nezinsiza zokushintshwa kwe-voltage ephezulu.
3. I-Aerospace kanye Nokuvikela:
I-Radar Windows ne-Radomes: Bonisa izakhiwo ezinhle kakhulu ezibonisa amaza amagagasi (ezibonisa ngale kuma-microwave) futhi ingamelana nokushaqeka kwe-aerodynamic thermal, esetshenziswa kumicibisholo, i-radar, nezinye izinto zokusebenza.
Izithambisi Ezisezingeni Eliphezulu: Zisetshenziswa kumabherengi, amalayili aqondisayo, nezinye izimo ezinzima.
Icubungula izinyathelo zokuphepha:Nakubai-boron nitride
eyaziwa ngokuthi "i-ceramic ephathekayo kalula," amaphuzu alandelayo asadinga ukunakwa ngesikhathi sokucubungula kwangempela:
Ukukhethwa kwamathuluzi: Insimbi enesivinini esiphezulu noma amathuluzi e-carbide ayanconywa.
