Semicera Energy Technology Co., Ltd ndiwotsogola wotsogola wokhazikika pazakudya zowotcha komanso zida zapamwamba za semiconductor.Tadzipereka kuti tipereke zinthu zapamwamba kwambiri, zodalirika, komanso zatsopano pakupanga semiconductor,mafakitale a photovoltaicndi madera ena okhudzana.

Zogulitsa zathu zikuphatikiza zinthu za SiC/TaC zokutidwa ndi graphite ndi zinthu za ceramic, kuphatikiza zida zosiyanasiyana monga silicon carbide, silicon nitride, ndi aluminium oxide ndi zina.

Monga ogulitsa odalirika, timamvetsetsa kufunikira kwa zinthu zogwiritsidwa ntchito popanga, ndipo tadzipereka kupereka zinthu zomwe zimakwaniritsa miyezo yapamwamba kwambiri kuti tikwaniritse zosowa za makasitomala athu.

Silicon nitride yophatikizidwa ndi silicon carbide kiln ili ndi mawonekedwe amphamvu ya kutentha kwambiri, kukana kwamphamvu kwamafuta, kusinthika kosavuta, kukana kwa okosijeni, kukana kwa dzimbiri, kuwongolera kwamafuta abwino ndi zina zotero.

Zizindikiro zazikulu za ntchito

mankhwala chimagwiritsidwa ntchito ceramic akupera gudumu, mankhwala mkulu zotayidwa zadothi mpira, zotayidwa zadothi mpira, ng'anjo mafakitale, ceramic zamagetsi, mkulu voteji zadothi magetsi zadothi, ware ukhondo, zadothi tsiku, nitride aloyi ndi ziwiya zadothi thovu ndi mafakitale ena.

Kukaniza kuvala kwa zinthu za Si3N4-SiC ndi 3.13 nthawi ya chitsulo chosamva kuvala (Crl5Mo3), ndipo kulemera kwake ndi 1/3 yokha ya chitsulo chosavala (Crl5Mo3).

Kuchepetsa kukana kwa dzimbiri kwa Si3N4-SiC ndi calcium carbide ndi alumina munjira zosiyanasiyana ndi motere:
