(BN hmoovTsim los ntawmWintrustek)
Ua tsaug rau nws cov khoom tshwj xeeb,boron nitride hmoovyog siv ntau yam kev lag luam thiab thev naus laus zis hauv lub npe "dawb graphene." Cov khoom siv crystalline no, tsim los ntawm nitrogen thiab boron atoms txuas los ntawm cov ntawv cog lus muaj zog, ua kom pom cov graphite thiab nthuav tawm kev ua tau zoo hauv ntau yam, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub no.
Qhov zoo:
Nws ua haujlwm raws li hluav taws xob insulator.
Nws muaj chemical inertness zoo heev.
Nws muaj kev sib txhuam coefficients tsawg (0.5-0.70) thiab zoo lubrication zoo.
Nws qhia kev ruaj ntseg ntawm qhov kub thiab txias.
Nws muaj zog load-bearing muaj peev xwm.
Nws yog ib qho zoo thermal conductor, uas ua rau kom zoo dua tshav kub dissipation.
Nws cov yam ntxwv muaj xws li qis thermal expansion thiab qis dielectric tas li.
Nws yog ib qho yooj yim machinable nyob rau hauv ib tug kub pressed daim ntawv, tso cai rau cov creation ntawm complex duab.
Nws yog non-wetting thiab heev resistant rau tshuaj tua kab mob. Cov iav, ntsev, thiab cov hlau feem ntau yuav tsis moisten nws.
Daim ntawv thov:
Thermal Management Materials: Fillers siv thermally conductive silicone roj, yas, los yog ceramic substrates kom dissipate cua sov hauv CPUs, LEDs, 5G RF khoom, thiab lwm yam kev siv.
High-Temperature Metallurgy thiab Kev Ua Haujlwm: Pom muaj nyob rau hauv cov neeg ua haujlwm tso tawm casting, hlau evaporation nkoj, rauv hauv ob sab phlu, thiab thermocouple tiv thaiv raj.
High-Performance Lubricants: Muab lubrication zoo ib yam nyob rau hauv hnyav tej yam kev mob (siab kub, siab load), xws li aircraft thiab tsheb cav.
Tshuaj pleev ib ce thiab Kev Kho Tus Kheej: High-end foundations, hmoov, thiab lwm yam khoom tau txais txiaj ntsig los ntawm nws cov lubricating xav, gloss, thiab adsorption zoo.
Polymer Composite Materials: Txhim kho cov thermal conductivity, mechanical zog, thiab nplaim retardancy ntawm engineering plastics siv nyob rau hauv daim ntawv thov xws li hluav taws xob ntim.
Ceramics thiab Refractory Materials: Siv los ua ib qho ntxiv los txhim kho sinterability, thermal shock resistance, thiab mechanical qualities in ceramics.
Lwm yam kev siv:
Kev lag luam Nuclear: Siv los ua cov khoom siv neutron absorber thiab shielding khoom.
Kev them nyiaj yug catalyst: Siv nws qhov chaw tshwj xeeb ntawm thaj chaw thiab tshuaj lom neeg ruaj khov.
Semiconductor ua: Siv rau crucible coatings, substrates rau molecular beam epitaxy, thiab lwm yam.
Boron nitride hmoovmuaj cov khoom zoo xws li thermal conductivity, rwb thaiv tsev, lubrication, high-temperature resistance, thiab tshuaj stability, ua rau nws ib tug saj zawg zog cov ntaub ntawv rau kev soj ntsuam nrog ib tug ntau yam ntawm cov teeb meem nyob rau hauv tej yam kev ua hauj lwm heev nyob rau hauv niaj hnub kev lag luam. Nws tuaj yeem pom nyob rau hauv txhua yam los ntawm kev ua kom txias rau lub dav hlau, cov tshuaj pleev ib ce high-end, thiab nuclear reactors. Nrog rau kev nce qib ntawm kev npaj cov khoom siv thev naus laus zis thiab kev tshawb fawb tob tob, qhov "lub hnub qub khoom" yog qhov tseeb tias yuav ci ntsa iab dua nyob rau nthwv dej tom ntej ntawm kev tsim kho thev naus laus zis.
