Qhov sib txawv ntawm Boron Nitride thiab Silicon Carbide
Jan 17, 2024
Boron nitride thiab silicon carbide yog ob qho tseem ceeb ntawm cov khoom siv ceramic nrog cov khoom sib txawv thiab kev siv.
Boron nitride (BN) yog ib tug dav-bandgap semiconductor uas yog tshuaj thiab thermally ruaj khov, hluav taws xob insulating, thiab optically pob tshab. Nws muaj cov khoom siv zoo heev, suav nrog lub zog siab, hardness, toughness, thiab hnav tsis kam. BN yog siv rau ntau yam kev siv, xws li cov txheej txheem kub kub, cov cuab yeej txiav, cov khoom siv ceramic, cov khoom siv hluav taws xob, thiab cov rwb thaiv tsev. Nws kuj tseem siv rau hauv cov tshuaj pleev ib ce thiab cov roj nplua nyeem ua cov tshuaj tsis muaj tshuaj lom rau talc.
Silicon carbide (SiC) kuj yog ib tug dav-bandgap semiconductor uas yog tshuaj thiab thermally ruaj khov, tab sis tsis zoo li BN, nws yog ib tug zoo conductor ntawm hluav taws xob. SiC muaj lub zog siab, hardness, thiab thermal conductivity, nrog rau nruab nrab toughness thiab hnav tsis kam. Nws yog siv rau ntau yam kev siv, xws li cov ntaub ntawv abrasive, refractory thiab ceramic composites, electronics, thiab cov khoom siv fais fab. SiC kuj tseem siv nyob rau hauv kev lag luam automotive raws li lub teeb yuag thiab cov khoom kub-resistant rau cov tshuab nres thiab cov pa tawm.
Hauv cov ntsiab lus, BN thiab SiC yog ob qhov sib txawv tsis tau txais cov ntaub ntawv pub dawb nrog cov khoom tshwj xeeb thiab kev siv. Lawv sawv cev rau chav kawm ntawm cov ceramics siab heev uas muaj ntau yam zoo dua li cov ntaub ntawv ib txwm muaj, xws li hlau, polymers, thiab iav. Ob leeg cov ntaub ntawv muaj lub neej yav tom ntej nyob rau hauv ntau yam kev lag luam thiab kev lag luam, thiab lawv txoj kev txhim kho txuas ntxiv thiab kev sib koom ua ke yuav ua rau muaj kev cuam tshuam ntxiv hauv kev tshawb fawb thiab thev naus laus zis.
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.
