Boron Nitride Microstructure Tus yam ntxwv
Nov 13, 2023
Boron nitride yog qhov sib xyaw ntawm boron thiab nitrogen nrog cov qauv siv lead ua tshwj xeeb uas ua rau nws cov khoom tshwj xeeb. Nws cov qauv microscopic yog tus cwj pwm los ntawm hexagonal txheej ntawm boron thiab nitrogen atoms, teem rau hauv ib qho honeycomb lattice. Cov qauv no zoo ib yam li cov qauv ntawm graphene, tab sis nrog boron thiab nitrogen atoms alternating carbon atoms. Cov boron-nitrogen bonds muaj zog thiab luv dua li cov pa roj carbon-carbon bonds hauv graphene, ua rau cov khoom muaj zog thiab ruaj khov dua.
Ib qho tseem ceeb tshaj plaws ntawm cov qauv microscopic ntawm boron nitride yog nws cov thermal conductivity zoo heev. Cov qauv honeycomb lattice tso cai rau kev hloov pauv sai thiab muaj txiaj ntsig los ntawm cov khoom siv, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov uas xav tau cov thermal conductivity. Tsis tas li ntawd, boron nitride lattice qauv yog cov tshuaj tsis muaj zog, ua rau nws tiv taus tshuaj lom thiab xeb.
Boron nitride kuj muaj cov khoom siv hluav taws xob zoo heev. Lub hexagonal lattice qauv ua rau muaj qhov dav bandgap, ua boron nitride insulator es tsis yog tus neeg xyuas pib. Cov cuab yeej no ua rau nws zoo tagnrho rau kev siv hluav taws xob rwb thaiv tsev, xws li hauv cov khoom siv hluav taws xob high-voltage.
Zuag qhia tag nrho, cov qauv microscopic ntawm boron nitride yog qhov tshwj xeeb thiab nws cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig zoo hauv ntau yam kev siv. Nws cov thermal conductivity, tshuaj inertness, thiab hluav taws xob rwb thaiv tsev cov khoom ua rau nws yog ib qho khoom siv tsim nyog rau kev siv hauv cov khoom siv hluav taws xob, kev siv kub, thiab ntau lwm yam kev siv hauv kev lag luam.
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.
