Yog vim li cas Boron Nitride, uas muaj cov qauv zoo ib yam li Graphene, uas tsis yog-Conductive

Boron nitride yog ib qho sib xyaw ua ke ntawm boron thiab nitrogen, uas zoo sib xws hauv cov qauv rau graphene. Ib yam li graphene, boron nitride muaj ob sab hexagonal lattice qauv, uas ua rau nws yog ib tus neeg sib tw zoo tshaj plaws rau ntau yam kev siv, suav nrog hluav taws xob thiab optics. Txawm li cas los xij, tsis zoo li graphene, boron nitride yog ib qho insulator thiab tsis ua hluav taws xob.

Yog vim li cas rau qhov sib txawv no nyob rau hauv cov qauv hluav taws xob ntawm boron nitride. Thaum graphene muaj delocalized pi-electron system uas pab txhawb kev thauj mus los ntawm electron, boron nitride muaj qhov dav bandgap thiab ntau lub zog hluav taws xob hauv zos. Qhov no txhais tau hais tias cov khoom siv hluav taws xob tsis tuaj yeem txav mus los ywj pheej hauv cov khoom siv thiab tsis ua rau nws cov hluav taws xob conductivity.

Lwm qhov laj thawj rau boron nitride cov khoom insulating yog nws cov tshuaj sib txuas. Lub compound yog tsim los ntawm alternating boron thiab nitrogen atoms uas yog covalently bonded nyob rau hauv lub lattice. Cov ntawv cog lus muaj zog no tuav cov atoms nruj rau hauv qhov chaw thiab tiv thaiv cov hluav taws xob los ntawm kev txav mus los ywj pheej, uas ntxiv rau cov khoom siv tsis zoo.

Txawm hais tias nws tsis muaj hluav taws xob conductivity, boron nitride tseem yog ib qho khoom siv zoo kawg thiab muaj txiaj ntsig. Nws cov thermal conductivity, tsis tshua muaj coefficient ntawm thermal expansion, thiab zoo heev mechanical zog ua rau nws yog ib tug zoo heev neeg sib tw siv nyob rau hauv high-kub daim ntaub ntawv, xws li cov dab dej kub thiab insulators. Tsis tas li ntawd, nws cov khoom ua ib qho insulator ua rau nws muaj cov khoom siv hluav taws xob zoo hauv cov khoom siv hluav taws xob thiab lwm yam kev siv hluav taws xob uas xav tau kev rwb thaiv tsev.

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.
