Cov yam ntxwv thiab qhov zoo ntawm Boron Nitride Ceramics
Oct 11, 2023
Boron nitride ceramics, tseem hu ua BN ceramics, yog hom khoom siv ceramics siab heev nrog ntau yam khoom zoo thiab zoo. Cov ceramics no yog tsim los ntawm synthesizing molten boron nrog nitrogen nyob rau hauv lub cub tawg thiab ces txias qhov sib tov kom solidify nws mus rau hauv ib tug ruaj khov ceramic daim ntawv.
Ib qho ntawm cov khoom tseem ceeb ntawm BN ceramics yog lawv qhov tshwj xeeb thermal thiab tshuaj lom neeg ruaj khov. Lawv muaj qhov melting point ntawm 3000 degree thiab tuaj yeem tiv taus qhov kub txog li 2000 degree hauv lub tshuab nqus tsev lossis inert cua tsis muaj kev puas tsuaj loj. Lawv yog cov resistant rau corrosion, oxidation, thiab acidity, ua rau lawv zoo tagnrho rau siv nyob rau hauv hnyav industrial cheeb tsam xws li tshuaj ua cov nroj tsuag, semiconductor fabrication, thiab aerospace daim ntaub ntawv.
Lwm qhov txiaj ntsig tseem ceeb ntawm BN ceramics yog lawv cov khoom tshwj xeeb hluav taws xob rwb thaiv tsev. Lawv muaj qhov tsis tshua muaj dielectric tsis tu ncua thiab poob, ua rau lawv zoo tagnrho rau kev siv hluav taws xob thiab hluav taws xob siv hluav taws xob uas yuav tsum muaj kev rwb thaiv tsev siab. Qhov no kuj ua rau lawv muaj txiaj ntsig zoo rau kev siv hauv cov ntawv siv hluav taws xob siab thiab ua cov dab dej kub hauv cov khoom siv hluav taws xob uas muaj kev tswj xyuas thermal yog qhov tseem ceeb los tiv thaiv overheating.
BN ceramics kuj tseem muaj roj nplua nyeem thiab muaj cov khoom zoo ntawm tus kheej lubricating. Lawv tuaj yeem siv los ua cov txheej txheem txiav cov cuab yeej los txhim kho lawv cov kev hnav tsis kam thiab ua kom ntev lawv lub neej. Tsis tas li ntawd, lawv muaj kev sib txhuam qis thiab tuaj yeem siv tau rau hauv cov kabmob thiab cov zawv zawg los txhim kho lawv cov kev ua tau zoo.
Hauv kev xaus, BN ceramics muaj cov khoom tshwj xeeb thiab qhov zoo uas ua rau lawv xav tau ntau yam kev lag luam thiab kev siv hluav taws xob. Lawv tshwj xeeb thermal thiab tshuaj stability, hluav taws xob rwb thaiv tsev, thiab lubrication ua rau lawv superior rau ntau lwm yam ntaub ntawv uas tam sim no siv nyob rau hauv cov ntaub ntawv zoo sib xws. Yog li ntawd, BN ceramics tau npaj los ua cov khoom tseem ceeb hauv kev tsim 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.
