Thermal conductivity ntawm Silicon Carbide

Silicon carbide (SiC) cov khoom lag luam paub txog lawv cov thermal conductivity zoo, ua rau lawv muaj kev xaiv nrov rau cov ntawv thov uas xav tau kev hloov hluav taws xob zoo. SiC yog cov khoom siv ceramic nrog lub siab melting point thiab zoo heev hardness, uas ua rau nws zoo tagnrho rau siv nyob rau hauv high-temperature ib puag ncig.

Ib qho ntawm qhov zoo tshaj plaws ntawm SiC cov khoom yog lawv lub peev xwm los hloov cov cua sov sai. Qhov no yog vim ib feem ntawm lawv cov qauv siv lead ua tshwj xeeb, uas tso cai rau kev thauj mus los phonon zoo. Phonons yog lub luag haujlwm tseem ceeb ntawm lub zog hluav taws xob hauv cov khoom khib nyiab, thiab SiC cov qauv siv lead ua ua rau lawv mus tau sai thiab ua tau zoo thoob plaws hauv cov khoom.

Ntxiv nrog rau lawv cov thermal conductivity, SiC cov khoom kuj tseem tiv taus thermal shock. Qhov no txhais tau tias lawv tuaj yeem tiv taus kev hloov pauv sai hauv qhov kub thiab txias yam tsis muaj kev puas tsuaj. Qhov no ua rau lawv xaiv qhov zoo tshaj plaws rau kev siv xws li cov khoom cua sov, thermal barriers, thiab cov dab dej kub.

Lwm qhov txiaj ntsig ntawm SiC cov khoom lag luam yog lawv cov kev tiv thaiv corrosion thiab tshuaj tua kab mob. Qhov no txhais tau hais tias lawv tsis cuam tshuam los ntawm feem ntau cov kua qaub, alkalis, thiab lwm yam tshuaj corrosive, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv ib puag ncig hnyav.

Zuag qhia tag nrho, SiC cov khoom lag luam muaj ntau yam thiab muaj ntau yam txiaj ntsig thaum nws los txog rau thermal conductivity thiab hloov tshav kub. Lawv cov khoom tshwj xeeb ua rau lawv xaiv qhov zoo tshaj plaws rau ntau yam kev siv, los ntawm kev lag luam mus rau aerospace thiab dhau mus. Nrog rau kev tshawb fawb thiab kev txhim kho txuas ntxiv mus rau SiC-raws li cov ntaub ntawv tshiab thiab thev naus laus zis, nws zoo li lawv siv yuav txuas ntxiv mus ntxiv rau xyoo tom ntej.

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.
