Izimfanelo Zokwakha kanye Nezinhlobonhlobo zePolymorphic ze-Boron Nitride Ceramics
Ukuguquguquka kwe-boron nitride kusuka ekhonweni layo lokwamukela izinhlaka zekristalu ezihlukene, ngayinye inezici ezihambisanayo zomzimba namakhemikhali. I-hexagonal boron nitride (h-BN), evame ukubizwa ngokuthi “i-graphite emhlophe,” ihlanganisa uhlaka olunezingqimba oludlulisa ukuthambisa okuhle kakhulu, ukunciphisa ukuhlikihla, kanye ne-high conductivity eshisayo ngenkathi kugcinwa ukufakwa kukagesi. I-cubic boron nitride (c-BN), 2futhi kuphela idayimane ngobulukhuni, isetshenziswa kakhulu ekunciphiseni amadivaysi nezinhlelo zokusebenza ezingajabulisi. I-Wurzite BN (w-BN) ibonisa izindlu ze-piezoelectric, okwenza kube kuhle kumayunithi ezinzwa ezinomfutho ophezulu namathuluzi e-optoelectronic. Lawa ma-polymorphs anika amandla ukwakheka kwezinto ze-ceramic ezikhethekile kakhulu ezilungiswe ukuze zidinga isimo sezentengiselwano.
Amasu Okukhiqiza kanye Nezithiyo Zempahla
Ukukhiqiza izinto ze-ceramic ze-boron nitride ze-premium kufaka phakathi ukwakheka okuyimpushana okuqondile, ukubumba, namasu sintering. I-h-BN ivame ukukhiqizwa ngokuphusha okushisayo noma ukugqugquzela ukucwiliswa kwe-plasma, kuyilapho i-c-BN idinga ingcindezi ephezulu, izinga lokushisa eliphezulu (I-HPHT) izindlela zokugcina isigaba sayo se-cubic. Ukufeza aminyene, Izitsha zobumba ze-BN ezingenasici zihlala ziyinselelo ngenxa yokuzabalaza okuphansi komkhiqizo kanye nokuthambekela ekuqondeni i-porosity.. Izithako ezifana ne-yttria noma i-alumina zivame ukwethulwa ukuze kuthuthukiswe ukuminyana ngaphandle kokufaka engozini ukusebenza okushisayo noma kukagesi.. Ucwaningo oluqhubekayo lugxile ekukhiqizeni okungeziwe, i-nanostructuring, kanye nezinhlanganisela ezixubene ukuze kwandiswe izinhlobonhlobo zamajiyometri nokusebenza kahle.
Izicelo Kumadivayisi Kagesi, Ama-semiconductors, kanye Nezinhlelo Zokuphatha Ezishisayo
Omunye wemisebenzi ebaluleke kakhulu yezinto zobumba ze-boron nitride uncike ezimbonini ze-electronics kanye ne-semiconductor., lapho ukuqapha okushisayo kanye nokuhlukaniswa kukagesi kubaluleke kakhulu. Ama-substratum e-h-BN asetshenziswa kancane kancane kumamojula wamandla, Izingxenye ze-RF, kanye nezinqwaba ze-LED ngenxa ye-thermal conductivity ephawulekayo kanye nezindawo zokuhlala ze-dielectric noma zezohwebo. Kuzinqubo zokukhula kwekristalu ye-semiconductor– njengokudweba kwe-Czochralski noma ukuqiniswa kokuqondisa– Iziphambano ze-BN zenza ukuphatha okuthile kokuncibilika okungangcolisi. Ngaphezu kwalokho, Izendlalelo ze-BN zefilimu elincanyana zisebenza njengezithiyo zokusabalalisa kanye nokumbozwa kokudlula kumasekhethi ahlanganisiwe, ukuthuthukisa ukwethembeka kwethuluzi ngaphansi kwezimo ezinzima zokusebenza.
Ukusetshenziswa kwe-Aerospace, Ukuvikelwa, kanye neNuclear Technologies
Imikhiqizo yobumba ye-Boron nitride nayo idlala umsebenzi obalulekile emkhathini, ukuzivikela, kanye nezinhlelo zamandla e-athomu. Amakhono abo okumunca i-neutron abenza bafanelekele izinduku zokulawula kanye nokuvikela imikhiqizo ezitshalweni zamandla e-athomu.. Endizeni ye-hypersonic kanye nokuhlola indawo, Izinhlanganisela ze-BN zinikeza isisindo esilula, izingxenye ezivikeleke ngokushisa okushisayo ezikwazi ukubekezelela amazinga okushisa okungena kabusha adlulayo 2000 °C. Izinhlelo zokusebenza zamabutho ahlomile zihlanganisa ama-radar-transparent radoms, izigaxa zekhala le-rocket, kanye nezigqoko zokubhoboza izikhali ezenziwe ngezitsha zobumba eziqiniswe yi-c-BN. Njengoba ukuphepha nokuvikeleka kuzwelonke kanye nezimakethe zendawo zithuthuka, Isidingo semikhiqizo esekwe ku-BN kulindeleke ukuthi yande kakhulu.
Okusungulwe Kwezisetshenziswa Zemishini Nezimboni Zokucubungula
( I-Boron Nitride Ceramic)
I-cubic boron nitride (c-BN) empeleni iguqule izimboni zemishini nezinsimbi ngenxa yokuqina kwayo okumangalisayo nokuphepha okushisayo.. c-BN cutting devices outshine typical tungsten carbide and also some diamond devices when machining ferrous alloys, as they do not chemically react with iron at heats.
