Boron Nitride yog ib qho khoom siv hluav taws xob zoo tshaj plaws uas muaj nyob rau hauv cov khoom thiab hmoov.Nws cov khoom tshwj xeeb - los ntawm lub peev xwm kub kub thiab cov thermal conductivity kom yooj yim machinability, lubricity, tsis tshua muaj dielectric tas li thiab superior dielectric zog - ua rau boron nitride yog cov khoom zoo heev.
Nyob rau hauv nws cov khoom, boron nitride feem ntau hu ua "dawb graphite" vim hais tias nws muaj ib tug microstructure zoo ib yam li cov graphite.Txawm li cas los xij, tsis zoo li graphite, boron nitride yog ib qho hluav taws xob zoo heev uas muaj qhov kub ntawm oxidation ntau dua.Nws muaj cov thermal conductivity siab thiab zoo thermal poob siab tsis kam thiab tuaj yeem ua tau yooj yim machined kom kaw kam rau ua txhua yam zoo.Tom qab machining, nws yog npaj rau kev siv yam tsis muaj kev kho cua sov ntxiv los yog tua hluav taws.
Hauv inert thiab txo cov huab cua, AX05 qib ntawm Boron Nitride qib yuav tiv taus kub tshaj 2,000 ° C.Nws yog feem ntau siv los ua ib qho insulator nyob rau hauv kev sib cuag nrog tungsten thiab graphite electrodes ntawm cov kub.
Txhua qib Boron Nitride tuaj yeem siv rau hauv oxidizing cua mus txog 750 ° C.Nws tsis ntub los ntawm feem ntau cov hlau molten thiab slags thiab siv tau rau hauv kev sib cuag nrog feem ntau molten hlau xws li txhuas, sodium, lithium, silicon, boron, tin, germanium, thiab tooj liab.
General Boron Nitride Properties
Txhawm rau ua cov duab zoo, BN hmoov thiab cov ntawv khi yog kub-nias hauv cov ntawv loj txog 490mm x 490mm x 410mm ntawm qhov siab txog 2000 psi thiab kub txog 2000 ° C.Cov txheej txheem no tsim cov khoom siv uas tuab thiab yooj yim machined thiab npaj siv.Nws muaj nyob rau hauv txhua yam kev cai zoo uas tuaj yeem ua machined thiab muaj cov yam ntxwv tshwj xeeb thiab lub cev muaj zog uas ua rau nws muaj txiaj ntsig zoo rau kev daws teeb meem nyuaj hauv ntau hom kev lag luam.
