Synthesis Methods ntawm Silicon Carbide Ceramics
Silicon carbide ceramics, tseem hu ua carborundum, yog ib hom khoom siv ceramic uas yog tsim los ntawm silicon thiab carbide. Lawv muaj kev sib xyaw tshwj xeeb ntawm cov khoom xws li lub zog siab, hardness, thiab tshuaj lom neeg ua haujlwm, ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev siv kub thiab abrasive.
Muaj ntau txoj hauv kev ntawm kev sib txuas ntawm silicon carbide ceramics, txhua tus muaj nws tus kheej zoo thiab kev txwv. Ib txoj hauv kev zoo tshaj plaws yog cov txheej txheem kev sib txuas ntawm cov tshuaj tiv thaiv, uas cuam tshuam cov tshuaj tiv thaiv ntawm silicon thiab carbon ntawm qhov kub thiab txias hauv qhov muaj cov catalyst. Cov khoom siv ua tau yog qhov sib zog ua tuab, muaj cov qauv uas tuaj yeem ua tiav kom ua tiav qib siab ntawm lub zog thiab hardness.
Lwm txoj kev yog cov txheej txheem sintering, uas cuam tshuam nrog kev sib xyaw ntawm silicon carbide hmoov rau hauv lub cev ntsuab ua raws li cua sov hauv qhov chaw tsis muaj roj. Cov cua kub txhawb txoj kev ua kom muaj kev cuam tshuam thiab kev sib tham ntawm cov lus, ua rau muaj cov qauv sib xyaw ceramic.
Ib txoj hauv kev tsis ntev los no yog cov txheej txheem plasma sintering, uas siv cov hluav taws xob tawm hluav taws xob kom ceev cov roj silicon carbide hmoov. Qhov no ua rau cov khoom lag luam zoo thiab cov khoom siv ntom ntom ntom uas ua rau cov khoom ua haujlwm txhim kho neeg kho tshuab.
Txawm hais tias siv txoj kev twg los xij, kev sib xyaw ntawm silicon carbide ceramics yuav tsum tau ua tib zoo tswj cov kev ua haujlwm kom ua tiav cov khoom xav tau. Kev nce qib hauv kev siv thev naus laus zis thiab kev tsim cov txheej txheem tshiab txuas ntxiv txhim kho cov khoom thiab kev siv ntawm silicon carbide ceramics.
Shengyang New Materials Co., Ltd. tau cog lus los ua silicon carbide thiab silicon carbide ua cov khoom, thiab tuaj yeem kho ntau yam silicon carbide Cheebtsam raws li cov neeg siv khoom xav tau. Yog tias tsim nyog, thov hu rau peb.

Zuag qhia tag nrho, cov synthesis ntawm silicon carbide ceramics muaj peev xwm tseem ceeb rau kev siv nyob rau hauv ntau hom kev lag luam. Lawv cov khoom sib xyaw tshwj xeeb ua rau lawv muaj txiaj ntsig zoo rau qhov kub thiab txias, abrasive, thiab corrosive ib puag ncig. Nrog rau kev tshawb fawb thiab kev txhim kho txuas ntxiv, cov ntawv thov rau silicon carbide ceramics tau teeb tsa kom nthuav dav, muab txoj hauv kev tshiab rau kev tsim kho tshiab thiab kev vam meej.
