Silicon carbide ceramic ndiro

Munyika yekugadzirwa kwakanyatsogadzirwa, kune zvinhu zvinotsigira zvinyararire kukurudzirwa kwemabhizimisi akawanda epamusoro - yakaoma kudarika simbi, inopisa kupisa kupfuura graphite, asi nguva dzose inochengetedza muviri usina kusimba. Ichi chisilicon carbide ceramic ndiro, "metamaterial" inokosha muindasitiri yemazuva ano.
1, Zvipo zvechisikigo uye kupenya kwehuchenjeri hwevanhu
Silicon carbide (SiC) haisi chigadzirwa netsaona murabhoritari. Kare muna 1893, masayendisiti akawana iyi mineral inowanzoitika. Mazuva ano, nekushandisa tekinoroji yepamusoro yekugadzira tekinoroji kusanganisazve silicon jecha uye kabhoni masosi pakupisa kwakanyanya, maindasitiri egiredhi silicon carbide ceramics ane mashandiro arinani anogadzirwa. Ichi chinyorwa chinonyatso kusanganisa kugadzikana kwekeramics nehunhu hwesemiconductors, ichigadzira yakasarudzika zvinhu gene.
2, Decrypt iwo mashanu epakati mabhenefiti
1. Muchengeti wekushisa kwepamusoro
Pasi pemamiriro akanyanya e1350 ℃, simbi dzakajairwa dzakatopfava uye dzakaremara, nepo silicon carbide ceramic mahwendefa achiri kukwanisa kuchengetedza kutendeseka kwechimiro. Iyi innate tembiricha yekudzivirira inoita kuti ive sarudzo yakanaka kuminda yakadai semidziyo yekunyungudika uye injini dzemuchadenga.
2. Super yakasimba inodzivirira nhovo
Kuomarara, kwechipiri chete kudhaimondi, kunobvumira silicon carbide mahwendefa kuti arambe kukukurwa uye chidimbu chinokanganisa chesimbi yakanyungudutswa. Pamutsetse wekukanda aluminium, hupenyu hwayo hunowedzerwa nekanopfuura ka5 kana zvichienzaniswa neyechinyakare refractory zvinhu.
3. Unyanzvi mukupisa conduction
Kusiyana ne "insulation" zvimiro zveakajairwa ceramics, silicon carbide ceramics ine yakanakisa yekupisa conductivity. Izvi "zvinofema" zvinhu zvinogona kukurumidza kutamisa kupisa paunenge uchichengetedza kugadzikana kwayo, zvichiita kuti zvive zvakanyanya kushanda mumunda we semiconductor heat dissipation.

4. Huremu piyona
Panguva imwecheteyo, uremu hwayo hunongova chikamu chimwe chete muzvitatu chesimbi. Ichi chimiro che "kusimudza zvinhu zvinorema zvishoma" chinounza budiriro yekudzikisa huremu mhinduro kuminda senge midziyo yesimba nyowani uye njanji.
5. Chemical Defender
Yakatarisana nezvinosvibisa midhiya, silicon carbide ceramics inoratidza kugadzikana kunoshamisa. Muchigadzirwa chemakemikari, zvakafanana nemurindi asingamboita ngura, achivimbisa kuchengetedzwa kwekugadzirwa.
3、 Isingaperi mikana yekuchinja ramangwana
Kubva pane inotakura-inotakura substrate ye photovoltaic masero kusvika kune inopfeka-inodzivirira zvikamu zvechaiyo muchina, kubva pakupisa kupisa base ye semiconductor machipisi kusvika kune yekusefa module yemidziyo yekudzivirira kwezvakatipoteredza, silicon carbide ceramic mahwendefa ari kutsanangura patsva miganhu yekushanda kwezvinhu zveindasitiri. Muminda yehungwaru senge simba idzva, ruzivo rwemagetsi, uye yepamusoro-yekupedzisira midziyo, silicon carbide ceramic zvinhu zviri kutyaira chinyararire kusimudzira maindasitiri.
Semugadziri wetekinoroji akabatanidzwa zvakanyanya mumunda weakakosha ceramics, isu tinogara takazvipira kusundira kuita kwesilicon carbide zvinhu kusvika zvakanyanyisa. Nekuenderera mberi nekuvandudza sintering maitiro uye pamusoro pekurapa maitiro, yega ceramic board inova indasitiri yemifananidzo inogona kumira muyedzo wenguva. Ramangwana rasvika, ngatipupurirei pamwe chete runako rwakasiyana rwesilicon carbide ceramics iri kutumbuka mune mamwe minda.
Shandong Zhongpeng anogara achiomerera kune iyo pfungwa ye "material innovation inofambisa kufambira mberi kwemaindasitiri", uye inotarisira kushanda nevadyidzani vepasirese kuti vaongorore kusingaperi kwekushandisa mikana yesilicon carbide ceramics.
