Nyob rau hauv lub teb ntawm advanced cov ntaub ntawv,silicon carbide (SiC) thiab silicon nitride (Si3N4) ceramicstau dhau los ua ob qhov tseem ceeb tshaj plaws, txhua tus muaj cov khoom tshwj xeeb thiab kev siv. Nkag siab qhov sib txawv ntawm ob lub ceramics no yog qhov tseem ceeb rau kev lag luam uas vam khom cov ntaub ntawv ua tau zoo. Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd. yog lub tuam txhab high-tech tshwj xeeb hauv kev tsim cov silicon carbide ceramics, ua si lub luag haujlwm tseem ceeb hauv daim teb no, muab kev nkag siab tob rau hauv cov khoom thiab kev siv ntawm cov ntaub ntawv no.

Silicon carbide ceramics paub txog lawv qhov tshwj xeeb hardness thiab thermal stability. Lawv muaj cov silicon thiab carbon, uas ua ke los ua ib qho chaw uas muaj kev hnav zoo heev thiab kev tiv thaiv corrosion. Qhov no ua rau silicon carbide ceramics zoo tagnrho rau cov ntawv thov hauv cov cheeb tsam hnyav xws li aerospace, automotive thiab semiconductor industries. Silicon carbide siab thermal conductivity kuj tso cai rau nws kom dissipate tshav kub zoo, ua rau nws zoo tagnrho rau high-temperature daim ntaub ntawv. Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd. siv cov khoom no los tsim cov khoom zoo silicon carbide ceramics uas ua tau raws li qhov xav tau ntawm ntau yam kev lag luam.

Silicon nitride ceramics, ntawm qhov tod tes, muaj cov khoom siv zoo heev, suav nrog lub zog siab thiab tawv. Si3N4 ceramics, muaj li ntawm silicon thiab nitrogen, tshwj xeeb tshaj yog tiv taus thermal shock thiab muaj qis coefficient ntawm thermal expansion piv rau silicon carbide. Qhov no ua rau silicon nitride ceramics yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau cov ntaub ntawv los tiv thaiv qhov kub thiab txias, xws li roj turbines thiab cov cuab yeej txiav. Silicon nitride qhov tshwj xeeb microstructure kuj muab nws zoo heev tawg toughness, ua rau nws yog ib qho khoom ntawm kev xaiv rau kev lag luam uas yuav tsum tau cov khoom ruaj khov.

Thaum sib piv ob cov ntaub ntawv, ib qho ntawm qhov sib txawv tseem ceeb tshaj plaws yog nyob rau hauv lawv cov khoom thermal. Silicon carbide ceramics tuaj yeem tiv taus qhov kub siab dua li silicon nitride ceramics, ua rau lawv tsim nyog siv rau hauv cov ntawv thov kub heev. Txawm li cas los xij, silicon nitride lub peev xwm los tiv thaiv thermal shock ua rau nws muaj txiaj ntsig zoo nyob rau hauv ib puag ncig nrog qhov kub thiab txias hloov pauv. Qhov kev sib txawv no yog qhov tseem ceeb rau cov kws tshaj lij thiab cov neeg tsim qauv thaum xaiv cov khoom siv rau ib daim ntawv thov tshwj xeeb, vim tias kev xaiv cov khoom tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev pabcuam lub neej.

Lwm qhov sib txawv loj ntawm silicon carbide thiab silicon nitride ceramics yog lawv cov tshuaj lom neeg ruaj khov. Silicon carbide tiv taus oxidation thiab tuaj yeem tswj nws cov khoom txawm tias nyob rau hauv ib puag ncig corrosive tshuaj. Qhov no ua rau nws zoo tagnrho rau kev siv tshuaj lom neeg thiab cov khoom siv hluav taws xob semiconductor. Hauv qhov sib piv, silicon nitride ceramics, thaum tshuaj lom neeg ruaj khov, yuav tsis ua haujlwm zoo hauv qee qhov chaw corrosive. Kev nkag siab txog cov khoom siv tshuaj lom neeg no yog qhov tseem ceeb rau kev lag luam ua haujlwm hauv cov xwm txheej nyuaj vim nws cuam tshuam rau kev xaiv cov khoom siv thiab cov khoom tsim.

Kev tsim cov txheej txheem rau silicon carbide thiab silicon nitride ceramics kuj txawv heev. Silicon carbide ceramics feem ntau yog tsim los ntawm sintering, txheej txheem uas muaj cua sov cov khoom mus rau qhov kub hauv qab nws cov ntsiab lus melting kom ua tiav qhov ntom ntom. Txoj kev no tuaj yeem tsim cov duab nyuaj thiab cov khoom siv ntom ntom ntom ntom. Hauv qhov sib piv, silicon nitride ceramics feem ntau yog tsim los ntawm kev sib xyaw ua ke ntawm cov hmoov ua thiab sintering cov tswv yim, nrog rau kev kub kub los yog kev sib koom ua ke. Cov kev sib txawv ntawm cov txheej txheem tsim khoom tuaj yeem cuam tshuam cov khoom kawg ntawm cov ceramic, nrog rau nws cov microstructure thiab txhua yam khoom.

Nyob rau hauv cov nqe lus ntawm tus nqi, silicon carbide ceramics zoo li yuav kim dua silicon nitride ceramics vim cov khoom siv raw thiab kev siv tshuab. Txawm li cas los xij, kev ua haujlwm ntev thiab ua haujlwm ntev ntawm silicon carbide tuaj yeem ua pov thawj qhov kev nqis peev ntau dua, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas tsis ua haujlwm tuaj yeem ua rau muaj kev poob qis lossis kev nyab xeeb. Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd. tsom rau kev muab cov kev daws teeb meem zoo uas tsis muaj kev cuam tshuam zoo, kom ntseeg tau tias cov neeg siv khoom tau txais txiaj ntsig zoo tshaj plaws rau lawv cov peev hauv silicon carbide ceramics.

Hauv cov ntsiab lus, qhov sib txawv ntawm silicon carbide ceramics thiab silicon nitride ceramics yog qhov tseem ceeb thiab tuaj yeem cuam tshuam rau lawv cov kev siv thoob plaws ntau yam kev lag luam. Silicon carbide ua tau zoo nyob rau hauv qhov kub thiab txias thiab chemically corrosive ib puag ncig, thaum silicon nitride nthuav tawm zoo heev toughness thiab tsis kam rau thermal shock. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau engineers thiab manufacturers thaum xaiv cov khoom siv rau cov ntawv thov tshwj xeeb. Raws li lub tuam txhab ua lag luam ntawm silicon carbide ceramics, Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd. tau cog lus los txhawb kev ua haujlwm ntawm cov ceramics siab heev, muab cov khoom zoo uas ua tau raws li cov kev xav tau ntawm kev lag luam niaj hnub no. Los ntawm kev siv cov khoom tshwj xeeb ntawm silicon carbide thiab silicon nitride, cov tuam txhab tuaj yeem txhim kho lawv cov qauv tsim thiab txhim kho kev ua tau zoo ntawm lawv cov khoom, thaum kawg ua kom muaj txiaj ntsig thiab kev ntseeg siab ntawm lawv cov haujlwm.
