Mapangidwe a tinthu tating'onoting'ono ta Coarse, apakati, ndi abwino a SiC ayenera kukhala 5:1:4. Black SiC nthawi zambiri amasankhidwa ngati zopangira zopangira njerwa za silicon carbide; mankhwala ake ali motere: SiC 98.0%, yaulere C 0.5%, Fe 0.2%, ndi SiO₂ 0.6% yaulere. Njira zopangira zimasiyanasiyana malinga ndi njira yolumikizirana. Chidule chachidule cha njira za njira zosiyanasiyana zolumikizirana ndi izi:
(1) Njerwa za Silicon nitride-zomangika za silicon carbide: Matupi obiriwira opangidwa kuchokera ku tinthu tating'ono ta SiC tosalala, zapakatikati, ndi zosalala bwino za silicon ufa amawotchedwa mumlengalenga wowona wa N₂ pa madigiri 1370 . Izi zimapanga njerwa yokhala ndi -SiC skeleton ndi - ndi -Si₃N₄ matrix. Zochepa zotsalira za silicon ndi SiO₂ zimakhalabe m'matrix; zokhudzana ndi zigawozi zimasiyana ndi wopanga.
(2) Njerwa za silicon carbide: SiC, silicon powder, ndi carbon powder zimasakanizidwa ndikuwumbidwa molingana ndi chiŵerengero chapadera, kenako zimawotchedwa pa 1400 digiri mu mpweya wochepetsetsa. Nthawi zambiri, kuwombera kumachitika ndi njerwa zokwiriridwa mu kaboni. Panthawi yowotcha, njerwa yokhala ndi -SiC skeleton ndi yabwino-yokongoletsedwa -SiC matrix imapangidwa. -SiC imapangidwa kudzera mu kachitidwe ka ufa wa silicon wokhala ndi ufa wabwino wa kaboni panthawi yowotcha; mankhwalawa mulinso pang'ono silicon yotsalira ndi mpweya.
(3) Silicon oxynitride-njerwa zomangika za silicon carbide: Pokonza batchi ya njerwa zimenezi, gawo la ufa wosalala wa silikoni wogwiritsidwa ntchito ndi wocheperapo kuposa la silicon carbide.
