Boron Nitride yog ib yam khoom siv ua los ntawm cov khoom siv ceramic uas muaj nyob rau hauv daim ntawv khov thiab hmoov. Nws cov yam ntxwv tshwj xeeb - los ntawm lub peev xwm kub siab thiab kev ua tau zoo ntawm cov cua sov mus rau kev siv tshuab yooj yim, lubricity, dielectric tsis tu ncua qis thiab lub zog dielectric zoo dua - ua rau boron nitride yog ib yam khoom zoo heev.
Hauv nws daim ntawv khov kho, boron nitride feem ntau hu ua "graphite dawb" vim nws muaj cov qauv me me zoo ib yam li graphite. Txawm li cas los xij, tsis zoo li graphite, boron nitride yog cov khoom siv hluav taws xob zoo heev uas muaj qhov kub oxidation siab dua. Nws muaj cov thermal conductivity siab thiab zoo thermal shock tsis kam thiab tuaj yeem ua tau yooj yim kom kaw qhov kam rau ua hauv txhua yam duab. Tom qab ua haujlwm, nws npaj txhij rau kev siv yam tsis muaj kev kho cua sov ntxiv lossis kev ua haujlwm tua hluav taws.
Hauv cov huab cua inert thiab txo qis, qib AX05 ntawm Boron Nitride qib yuav tiv taus qhov kub tshaj 2,000 ° C. Nws feem ntau yog siv ua cov insulator hauv kev sib cuag nrog tungsten thiab graphite electrodes ntawm cov kub ntawd.
Txhua qib Boron Nitride siv tau rau hauv cov huab cua oxidizing txog li 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 cov hlau molten suav nrog txhuas, sodium, lithium, silicon, boron, tin, germanium, thiab tooj liab.
Cov Khoom Siv Boron Nitride Dav Dav
Yuav kom ua tau cov duab khov kho, cov hmoov BN thiab cov khoom khi tau raug nias kub hauv cov billets txog li 490mm x 490mm x 410mm ntawm qhov siab txog li 2000 psi thiab qhov kub txog li 2000 ° C. Cov txheej txheem no tsim cov khoom siv uas ntom thiab yooj yim tshuab thiab npaj siv. Nws muaj nyob rau hauv yuav luag txhua yam kev cai duab uas tuaj yeem tshuab thiab muaj cov yam ntxwv tshwj xeeb thiab cov khoom siv lub cev uas ua rau nws muaj txiaj ntsig zoo rau kev daws cov teeb meem nyuaj hauv ntau yam kev siv hauv kev lag luam.
