I-nitride ye-boron enezinhlangothi eziyisithupha Impuphu (HBN) inomoya omuhle wokushisa, izakhiwo zomphetho, ukuqina kwamakhemikhali kanye nokuthambisa. Izinga lokushisa layo lokulwa nokugqwala lidlula u-2000°C, futhi ithambile kahle emazingeni okushisa aphezulu. Isetshenziswa kakhulu ekulungiseleleni i-cubic boron nitride, izembozo zokushisa okuphezulu, ama-filler, ama-hBN agglomerates, njll. I-Boron oxide
(1) Imboni yezinto eziqinile kakhulu. Isetshenziselwa ukulungiselela i-cubic boron nitride. I-cubic boron nitride iyi-hexagonal boron nitride engezwe nge-catalyst esekelwe ku-lithium noma i-magnesium, engaguqulwa ibe yi-cubic boron nitride ngaphansi kokushisa okuphezulu. Njengamanje, imboni yasekhaya idla amathani angaphezu kuka-400 e-hexagonal boron nitride minyaka yonke.
(2) Imboni yokupenda. Ngemva kokuba i-hBN igqokwe ngensimbi, izinto zobumba nezinye izinto, ingenza izinto zibe nokuthamba okuhle ebusweni kanye nokunganamatheli (ukukhululwa), futhi ingavimbela noma inciphise ukusabela kwamakhemikhali phakathi kwezinto nokuncibilika, futhi ithuthukise impilo yezinto; Izembozo ezintsha ezahlukahlukene eziphehla ukushisa zama-radiator nezingxenye ze-elekthronikhi ukwandisa ukushabalaliswa kokushisa. Ifanele ama-radiator ezimboni ze-photoelectric, amamojula okupholisa izingxenye ze-elekthronikhi, amamojula okupholisa amandla, ama-radiator ezimoto, ama-oyela okupholisa, ama-oyela egiya, nezinye izinhlobo zama-cooler.
(3) Imboni yezinto zikagesi. Uma isetshenziswa njengesigcwalisi sezinto ezisebenzisa ukushisa okuphezulu, i-hBN inokumelana okuhle nokushisa, ukumelana nokugqwala okuhle, i-coefficient yokwanda kokushisa okuphansi kanye nesilinganiso sokushisa esiphezulu. Iyinto efanelekile yokushisa futhi ingathuthukisa ukuhanjiswa kokushisa kwezingxenye zikagesi ezisekelwe ku-resin. Isilinganiso.
(4) Imboni yezimonyo esezingeni eliphezulu. Uma isetshenziswa njengesithako sokugcwalisa izimonyo esisezingeni eliphezulu, ingandisa ukunamathela namandla okufihla izimonyo, futhi inomuzwa omuhle wokushelela, okwenza izimonyo zibe zincane, kube lula ukuzisebenzisa, kube lula ukuzihlanza nokuzisusa, futhi kuyingozi emzimbeni womuntu. Njengamanje, imboni yezithako zokugcwalisa izimonyo esezingeni eliphezulu idla amathani angaphezu kuka-200 e-hexagonal boron nitride minyaka yonke.
(5) Imboni yezinto zokugcoba. Njengesengezo sezinto zokugcoba eziqinile neziwuketshezi. Ukwengezwa kwamafutha okugcoba kungathuthukisa ukusebenza kahle kukaphethiloli, kuthuthukise ukusebenza kwesilinda, futhi kube nemiphumela emihle yokonga amandla.
(6) Imboni ye-ceramic yobuchwepheshe obuphezulu, esetshenziselwa ukulungiselela ama-hBN agglomerate. Ama-hBN agglomerate anokushisa okuphezulu, ukusebenza kahle kakhulu kwezinga lokushisa eliphezulu, izakhiwo zikagesi neze-dielectric ezinhle kakhulu, futhi avame ukusetshenziselwa ukulungiselela izingxenye zokushisa okuphezulu kanye nokucindezela okuphezulu, izingxenye zikagesi ezishisa kakhulu, ama-crucibles kanye nezikhunta, kanye namafasitela okungena kwamanzi aphezulu kanye nokuqina okuphezulu. I-Missile radome, ifasitela le-antenna ye-microwave nezinye izingxenye.
