Cov khoom ntawm Silicon Carbide Hlau

Silicon carbide hlau, tseem hu ua carborundum, boasts exceptional hardness, thib ob tsuas yog pob zeb diamond. Qhov no hardness, ua ke nrog siab thermal conductivity, tshuaj inertness, thiab superior zog, ua rau nws zoo tagnrho rau kev thov. Nws qhov siab melting point (nyob ib ncig ntawm 2730 ° C) ntxiv rau nws qhov tsim nyog rau qhov kub thiab txias ib puag ncig. Cov qauv siv lead ua tshwj xeeb ntawm SiC ua rau muaj ntau yam polymorphs, txhua qhov nthuav tawm cov khoom sib txawv me ntsis, ua rau cov ntawv thov raug txiav raws li hom tshwj xeeb ntawm SiC siv. Cov khoom no ua rau nws tshwj xeeb tshaj yog haum rau ntau yam kev siv thoob plaws ntau qhov kev lag luam.

Txoj kev tsim khoom

Kev tsim tawm ntawm silicon carbide hlau koom nrog ntau txoj hauv kev, feem ntau yog cov txheej txheem Acheson, uas siv qhov kub thiab txias kom hnov ​​mob silica (SiO2) thiab carbon (C) hauv qhov cub hluav taws xob. Lwm txoj hauv kev suav nrog tshuaj lom neeg vapor deposition (CVD) thiab cov txheej txheem siab uas tso cai rau kev tsim cov khoom siv purity SiC siv hauv cov ntawv thov siab heev. Cov txheej txheem tshwj xeeb ua haujlwm nyob ntawm qhov xav tau purity thiab siv lead ua qauv ntawm cov khoom kawg, cuam tshuam rau cov nqi thiab daim ntawv thov.

Daim ntawv thov ntawm Silicon Carbide Hlau

Cov ntawv thov kev lag luam

Kev lag luam sector feem ntau siv silicon carbide hlau hauv ntau daim ntawv thov. Nws hardness ua rau nws yog ib qho tseem ceeb ntawm cov cuab yeej abrasive, sib tsoo lub log, thiab cov cuab yeej txiav. Cov tshuaj inertness yog ib qho tseem ceeb nyob rau hauv daim ntawv thov xws li high-kub crucibles thiab linings rau tshuaj reactors. Tsis tas li ntawd, nws muaj peev xwm tiv taus cov xwm txheej huab cua pom cov ntawv thov hauv ntau cov txheej txheem kev lag luam uas cov kav ntev thiab tsis kam yog qhov tseem ceeb.

Electronic Applications

Kev nce qib tsis ntev los no tau ua tiav silicon carbide hlau tus neeg tseem ceeb hauv kev lag luam electronics. SiC cov khoom siv hluav taws xob tshwj xeeb tso cai rau kev tsim cov khoom siv hluav taws xob siab, cov khoom siv siab xws li transistors thiab diodes. Cov Cheebtsam no tseem ceeb zuj zus hauv cov khoom siv hluav taws xob, muab cov txiaj ntsig zoo hauv kev ua haujlwm thiab kev ua tau zoo piv rau cov khoom siv silicon-based. Qhov no ua rau SiC tseem ceeb heev rau cov ntawv thov xws li tsheb hluav taws xob, hluav taws xob txuas ntxiv mus, thiab cov khoom siv hluav taws xob muaj zog. Inner Mongolia Xinxin Silicon Kev Lag Luam Co., Ltd.https://www.xinxinsilicon.com/) yog ib qho piv txwv ntawm ib lub tuam txhab koom nrog hauv kev tsim khoom thiab muab cov khoom zoo SiC rau cov ntawv thov.

Lwm Daim Ntawv Thov

Tshaj li kev lag luam thiab kev siv hluav taws xob, silicon carbide hlau nrhiav nws txoj hauv kev mus rau ntau qhov chaw. Nws biocompatibility ua rau nws haum rau qee yam kev siv biomedical, thaum nws cov cua sov thiab lub zog yog leveraged nyob rau hauv high-temperature daim ntaub ntawv xws li cov ntaub ntawv refractory thiab tiv thaiv txheej.
