Conductivity ntawm Boron Nitride
Apr 07, 2024
Boron nitride yog cov khoom siv hluav taws xob zoo heev. Cov cuab yeej no yog vim muaj cov qauv tshwj xeeb ntawm boron nitride, uas muaj alternating txheej ntawm boron thiab nitrogen atoms teem rau hauv hexagonal lattice, zoo ib yam li graphene.
Boron nitride muaj ib tug dav bandgap, uas txhais tau hais tias nws yuav tsum tau ib tug kuj loj npaum li cas ntawm lub zog los excite nws electrons thiab tso cai rau lawv ntws, muab cov khoom nws cov hluav taws xob insulating zog. Txawm li cas los xij, thaum boron nitride doped nrog lwm cov ntsiab lus xws li carbon, nws cov bandgap tuaj yeem txo qis, ua rau muaj hluav taws xob ntau ntxiv.
Boron nitride kuj muaj cov thermal conductivity siab, uas ua rau nws yog ib qho zoo heev thermal conductor thiab cov khoom zoo tagnrho rau siv nyob rau hauv high-temperature daim ntaub ntawv. Ntxiv mus, boron nitride muaj tshuaj lom neeg ruaj khov zoo, uas tso cai rau nws siv rau hauv qhov chaw hnyav, xws li cov uas pom hauv kev lag luam semiconductor.
Ntxiv nrog rau nws cov khoom siv hluav taws xob zoo heev, boron nitride muaj lwm yam khoom muaj txiaj ntsig, xws li lub zog siab thiab hardness, zoo thermal stability, thiab tsis tshua muaj kev sib txhuam coefficient. Cov khoom no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau ntau yam kev siv, xws li electronics thiab optics mus rau aerospace thiab cov khoom siv kho mob.
Hauv cov ntsiab lus, boron nitride yog cov khoom siv ntau yam thiab cog lus nrog cov hluav taws xob zoo heev thiab ntau yam ntawm lwm cov khoom muaj txiaj ntsig. Nws cov qauv tshwj xeeb thiab cov khoom ua rau nws yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv qib siab, thiab kev tshawb fawb tsis tu ncua yuav tsum nthuav tawm txawm tias muaj peev xwm siv tau rau cov khoom siv zoo kawg li no.
Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
