Za Silicon Carbide ndi SiC ceramics

Silicon Carbide ili ndi kukana kwamphamvu kwa dzimbiri, mphamvu zamakina apamwamba, matenthedwe apamwamba kwambiri, gawo lotsika kwambiri lakukula kwamafuta, komanso kukana kwamphamvu kwamafuta kuposa ma alumincell namet kutentha kwambiri. Silicon carbide imapangidwa ndi tetrahedra ya carbon ndi maatomu a silikoni okhala ndi zomangira zolimba mu crystal lattice. Izi zimapanga zinthu zolimba kwambiri komanso zamphamvu. Silicon carbide samawukiridwa ndi zidulo zilizonse kapena alkalis kapena mchere wosungunuka mpaka 800ºC. Mumlengalenga, SiC imapanga zokutira zoteteza za silicon oxide pa 1200ºC ndipo zimatha kugwiritsidwa ntchito mpaka 1600ºC. Kuthamanga kwapamwamba kwa kutentha komwe kumaphatikizidwa ndi kuwonjezereka kwamafuta ochepa komanso mphamvu zambiri zimapatsa zinthu izi kukhala zosagwirizana ndi kugwedezeka kwapadera. Zoumba za silicon carbide zokhala ndi zonyansa zazing'ono kapena zopanda malire za tirigu zimasunga mphamvu zawo mpaka kutentha kwambiri, kuyandikira 1600ºC popanda kutaya mphamvu. Kuyeretsedwa kwa Chemical, kukana kuukira kwamankhwala pakutentha, komanso kusunga mphamvu pakatentha kwambiri kwapangitsa kuti zinthu izi zidziwike kwambiri monga zogwirizira thireyi ya wafer ndi ma paddles mu ng'anjo za semiconductor. Thcell nameelectrical conduction of the material yapangitsa kuti igwiritsidwe ntchito polimbana ndi kutentha kwa ng'anjo zamagetsi, komanso ngati gawo lofunikira mu ma thermistors (kutentha kosiyanasiyana kopinga) ndi ma varistors (voltage variable resistors). Ntchito zina zimaphatikizapo nkhope zosindikizira, mbale zovala, ma bearings ndi machubu a liner.
