I-Boron Nitride Crucible BN Crucible
Umyalelo Womkhiqizo
I-Boron Nitride, eyaziwa nangokuthi i-BN, i-Hexagonal Boron Nitride (H-BN), kanye ne-Boron Nitride ecindezelwe ngokushisayo, iyi-ceramic ephuma kahle kakhulu yokuzigcoba ekwazi ukumelana namazinga okushisa aphakeme futhi igcine amandla ayo okugcoba endaweni ene-vacuum ephezulu.I-AEM's Boron Nitride crucibles yenziwe nge-boron nitride ecindezelwe ngokushisayo engenalutho.I-Hexagonal Boron Nitride (H-BN) iziphatha ngendlela efanayo ne-graphite ngokomshini kodwa inikeza ukumelana okuhle kakhulu kukagesi., futhi ingakhiqizwa njengemikhiqizo yokugcina ye-BN ngokuqondile njenge-crucible, isikebhe, ukunamathela, njll.
Izici Eziyinhloko
I-Boron nitride ine-insulation kagesi enhle, i-thermal conductivity, ukuqina kwamakhemikhali, futhi akukho ndawo encibilikayo esobala.Izinga lokushisa eliphezulu lokusetshenziswa ku-0.1MPA nitrogen lingafinyelela ku-3000 °C, endaweni yokunciphisa engathathi hlangothi, lingakwazi ukumelana nokushisa kuya ku-2000 °C, futhi izinga lokushisa lokusetshenziswa ku-nitrogen ne-argon lingafinyelela ku-2800 °C, futhi ukuzinza emkhathini we-oxygen impofu, futhi izinga lokushisa lokusebenzisa lingaphansi kuka-1000 °C.I-coefficient yokunweba ye-boron nitride ene-hexagonal ilingana naleyo yequartz, kodwa ukuqhutshwa kokushisa kuphindwe kashumi kune-quartz.
Ngaphezu kwalokho, i-hexagonal boron nitride ayincibiliki emanzini abandayo, futhi lapho amanzi abilisiwe, i-hydrolysis ihamba kancane futhi ikhiqiza inani elincane le-boric acid ne-ammonia.Ayisabeli nge-asidi ebuthakathaka kanye nesisekelo esiqinile ekamelweni lokushisa, inyibilika kancane ku-asidi eshisayo, futhi idinga ukuphathwa nge-sodium hydroxide encibilikisiwe ne-potassium hydroxide ukuze ibole.

Isicelo somkhiqizo
I-Boron nitride iwuhlobo lokumelana nokushisa okuphezulu, ukumelana nokugqwala, ukuguquguquka okuphezulu kwe-thermal, ukwahlukanisa okuphezulu kanye nokusebenza okuhle kakhulu kokugcotshwa kwento, isimo samanje sokwenza inqubo ibe lula, ukunciphisa izindleko zokukhiqiza, ukuthuthukisa impilo yesevisi yezingxenye yisona esisebenza kakhulu manje. isiqondiso socwaningo lwezinto ezinjalo.
(1) Ngokusebenzisa ukuqina okuhle kakhulu kwamakhemikhali e-boron nitride ene-hexagonal, ingasetshenziswa njengeziphambano, izikebhe, amapayipi okudiliva ensimbi awuketshezi, imibhobho yerokhethi, izisekelo zemishini enamandla amakhulu, amapayipi ensimbi ancibilikisiwe, izingxenye zephampu, isikhunta sensimbi, njll. ukuncibilikisa izinsimbi ezihwamukile.
(2) Kusetshenziswa ukumelana nokushisa nokugqwala kwe-boron nitride ene-hexagonal, izingxenye ezishisa kakhulu, izintambo zegumbi elivuthayo lamarokhethi, izihlangu zokushisa zemikhumbi-mkhathi, amajeneretha e-magnetocurrent, njll.
(3) Ngokusebenzisa ukufakwa kwe-hexagonal boron nitride, isetshenziswa kabanzi kuma-high-voltage high-frequency kagesi kanye ne-plasma arc insulators kanye nama-insulators ama-heaters ahlukahlukene, ukushisa ama-tube bushings kanye nokushisa okuphezulu, i-high-frequency, ukufakwa kwamandla kagesi aphezulu kanye izingxenye zokushisa ukushisa, kanye nokusetshenziswa kwe-high-frequency yezinto zokushisa zikagesi.
