I-nitride ye-boron enesiqingatha Umgubo (HBN) une-thermal conductivity elungileyo, iipropati zomphetho, uzinzo lweekhemikhali kunye nokuthambisa. Ubushushu bawo bokulwa ne-oxidation budlula i-2000°C, kwaye uthambisa kakuhle xa kushushu kakhulu. Usetyenziswa kakhulu ekulungiseleleni i-cubic boron nitride, ii-coatings zobushushu obuphezulu, ii-fillers, ii-hBN agglomerates, njl.njl. I-Boron oxide
(1) Ishishini lezinto eziqinileyo. Lisetyenziselwa ukulungiselela i-cubic boron nitride. I-cubic boron nitride yi-hexagonal boron nitride eyongezwe nge-lithium-based okanye i-magnesium-based catalyst, enokuguqulwa ibe yi-cubic boron nitride phantsi kobushushu obuphezulu. Okwangoku, ishishini lasekhaya lisebenzisa ngaphezu kweetoni ezingama-400 ze-hexagonal boron nitride minyaka le.
(2) Ishishini lokupeyinta. Emva kokuba i-hBN igqunywe ngentsimbi, iiseramikhi kunye nezinye izinto, ingenza ukuba izinto zibe nokuthamba okuhle komphezulu kunye nokunganamatheli (ukukhululwa), kwaye inokuthintela okanye inciphise impendulo yamakhemikhali phakathi kwezinto kunye nokunyibilika, kwaye iphucule ubomi bezinto; Iingubo ezintsha ezahlukeneyo eziqhuba ubushushu kwiiradiator kunye neendawo ze-elektroniki ukwandisa ukusasazwa kobushushu. Ifanelekile kwiiradiator zemizi-mveliso ze-photoelectric, iimodyuli zokuphola zezixhobo ze-elektroniki, iimodyuli zokuphola zamandla, iiradiator zemoto, ii-oyile zokuphola, ii-oyile zokuphola zebhokisi yegiya, kunye nezinye iintlobo zee-cooler.
(3) Ishishini lezinto ze-elektroniki. Xa lisetyenziswa njengesizalisi sezinto ezisebenzisa ubushushu obuphezulu, i-hBN inokumelana nobushushu okugqwesileyo, ukumelana nokugqwala okuhle, i-coefficient yokwandiswa kobushushu ephantsi kunye nesantya esiphezulu sobushushu. Lisixhobo esifanelekileyo somphetho wobushushu kwaye sinokuphucula ukuhanjiswa kobushushu kwezixhobo ze-elektroniki ezisekelwe kwi-resin. Isantya.
(4) Ishishini lezithambiso ezikumgangatho ophezulu. Xa lisetyenziswa njengesithambiso esikumgangatho ophezulu, linokunyusa ukunamathela kunye namandla okufihla izinto zokuthambisa, kwaye linomoya otyibilikayo, okwenza izithambiso zibe ncinci, kube lula ukuzisebenzisa, kube lula ukuzicoca nokuzisusa, kwaye ziyingozi emzimbeni womntu. Okwangoku, ishishini lezithambiso ezikumgangatho ophezulu lisebenzisa ngaphezu kweetoni ezingama-200 ze-hexagonal boron nitride ngonyaka.
(5) Ishishini lezinto zokuthambisa. Njengesithako sezinto zokuthambisa eziqinileyo nezilulwelo. Ukongezwa kweoyile yokuthambisa kunokuphucula ukusebenza kakuhle kwamafutha, kuphucule ukusebenza kwesilinda, kwaye kube nemiphumo emihle yokonga amandla.
(6) Ishishini le-ceramic elinobuchwepheshe obuphezulu, elisetyenziselwa ukulungiselela ii-hBN agglomerates. Ii-hBN agglomerates zinomoya ophezulu wokushisa, ukusebenza kakuhle kobushushu obuphezulu, iipropati zombane kunye ne-dielectric ezigqwesileyo, kwaye zihlala zisetyenziselwa ukulungiselela iinxalenye zobushushu obuphezulu kunye noxinzelelo oluphezulu lokusasaza ubushushu, iinxalenye zombane ezishushu kakhulu, ii-crucibles kunye nee-molds, kunye neefestile zokungena okuphezulu kunye nozinzo oluphezulu I-Missile radome, ifestile ye-antenna ye-microwave kunye nezinye iinxalenye.
