Zokhudza Silicon Carbide ndi SiC ceramics

Silicon Carbide imalimbana bwino ndi dzimbiri, imakhala ndi mphamvu zambiri zamagetsi, imayendetsa kutentha kwambiri, imakulitsa kutentha pang'ono, komanso imateteza kutentha kwambiri kuposa aluminiyamu yomwe imateteza kutentha kwambiri. Silicon carbide imapangidwa ndi ma atomu a kaboni ndi silicon okhala ndi ma bond amphamvu mu lattice ya kristalo. Izi zimapanga chinthu cholimba komanso cholimba. Silicon carbide siigwidwa ndi ma acid kapena alkali kapena mchere wosungunuka mpaka 800ºC. Mumlengalenga, SiC imapanga chophimba choteteza cha silicon oxide pa 1200ºC ndipo imatha kugwiritsidwa ntchito mpaka 1600ºC. Kuyendetsa kutentha kwakukulu komwe kumalumikizidwa ndi kukulitsa kutentha kochepa komanso mphamvu zambiri kumapatsa chinthuchi mawonekedwe abwino kwambiri olimbana ndi kutentha kwambiri. Zida za silicon carbide zokhala ndi zodetsa zochepa kapena zopanda malire zimasunga mphamvu zawo kutentha kwambiri, kufika 1600ºC popanda kutayika mphamvu. Kuyera kwa mankhwala, kukana kuukira kwa mankhwala kutentha, komanso kusunga mphamvu kutentha kutentha kwambiri kwapangitsa kuti chinthuchi chikhale chodziwika bwino ngati chothandizira ndi ma paddles mu uvuni wa semiconductor. Kutulutsa kwa zinthuzi pogwiritsa ntchito dzina la Thcell kwapangitsa kuti zigwiritsidwe ntchito potenthetsera zinthu zotsutsana ndi kutentha kwa uvuni wamagetsi, komanso ngati gawo lofunikira mu ma thermistors (ma resistor osinthasintha kutentha) ndi mu ma varistors (ma resistor osinthasintha magetsi). Ntchito zina zimaphatikizapo nkhope zomatira, mbale zovalidwa, ma bearing ndi machubu a liner.
