Silicon carbide imakhala ngati diamondi. Sikuti ndizopepuka kwambiri, komanso ndi zida zolimba kwambiri za ceramic ndipo zimakhala ndi matenthedwe abwino kwambiri, kukulitsa kwamafuta ochepa komanso kugonjetsedwa kwambiri ndi ma acid ndi ma sopo.
Ndi silicon carbide ceramics zinthu zakuthupi zimakhazikika mpaka kutentha kopitilira 1,400 ° C. High Young's modulus> 400 GPa imatsimikizira kukhazikika kwabwino kwambiri. Zinthu izi zimapangitsa silicon carbide kukonzedweratu kuti igwiritsidwe ntchito ngati zomangira. Silicon carbide masters corrosion, abrasion ndi kukokoloka mwaluso monga momwe zimakhalira ndi kuvala kosagwirizana. Zigawo zimagwiritsidwa ntchito muzomera zamankhwala, mphero, zowonjezera ndi zotulutsa kapena ngati ma nozzles, mwachitsanzo.
Mitundu ya SSiC (sintered silicon carbide) ndi SiSiC (silicon infiltrated silicon carbide) yadzikhazikitsa yokha. Yotsirizirayi ndi yoyenera kwambiri kupanga zigawo zikuluzikulu zazikuluzikulu.”
Silicon carbide ndi yotetezeka ku toxicologically ndipo ingagwiritsidwe ntchito m'makampani azakudya. Njira inanso yogwiritsira ntchito zida za silicon carbide ndiukadaulo wosindikizira wogwiritsa ntchito mayendedwe okangana ndi zisindikizo zamakina, mwachitsanzo pamapampu ndi makina oyendetsa. Poyerekeza ndi zitsulo, silicon carbide imathandizira mayankho azachuma kwambiri okhala ndi moyo wautali wa zida akagwiritsidwa ntchito ndi media zaukali, zotentha kwambiri. Silicon carbide ceramics ndi yabwinonso kuti igwiritsidwe ntchito pazovuta za ballistics, kupanga mankhwala, ukadaulo wamagetsi, kupanga mapepala komanso ngati zida zamapaipi.
Reaction bonded silicon carbide, yomwe imadziwikanso kuti siliconized silicon carbide kapena SiSiC, ndi mtundu wa silicon carbide womwe umapangidwa ndi zomwe zimachitika pakati pa porous carbon kapena graphite ndi silicon yosungunuka. Chifukwa cha zotsalira za silicon, reaction bonded silicon carbide nthawi zambiri imatchedwa siliconized silicon carbide, kapena chidule chake SiSiC.
Ngati silicon carbide yoyera imapangidwa ndi sintering ya silicon carbide powder, nthawi zambiri imakhala ndi mankhwala otchedwa sintering aids, omwe amawonjezedwa kuti athandizire njira yowotchera polola kutentha kwapansi. Mtundu uwu wa silicon carbide nthawi zambiri umatchedwa sintered silicon carbide, kapena kufupikitsidwa ku SSiC.
Mafuta a silicon carbide amachokera ku silicon carbide yopangidwa monga momwe tafotokozera m'nkhani ya silicon carbide.
