Game da Silicon Carbide da SiC ceramics

Silicon Carbide yana da kyakkyawan juriya ga lalata, ƙarfin injina, babban ƙarfin zafin jiki, ƙarancin haɓakar haɓakar thermal, kuma mafi kyawun juriyar girgiza zafi fiye da sunan alumincell mai tsananin zafi. Silicon carbide ya ƙunshi tetrahedra na carbon da silicon atoms tare da haɗin gwiwa mai ƙarfi a cikin lattice crystal. Wannan yana samar da abu mai wuya da ƙarfi. Silicon carbide ba a kai hari da kowane acid ko alkalis ko narkakken gishiri har zuwa 800ºC. A cikin iska, SiC yana samar da murfin silicon oxide mai kariya a 1200ºC kuma ana iya amfani dashi har zuwa 1600ºC. Babban haɓakar thermal haɗe tare da ƙarancin haɓakar thermal da ƙarfi mai ƙarfi suna ba wannan kayan keɓaɓɓen halayen juriya na zafin jiki. Silicon carbide yumbura tare da ƙanƙan ko babu ƙazanta iyakar hatsi suna kiyaye ƙarfinsu zuwa yanayin zafi sosai, yana kusantar 1600ºC ba tare da asarar ƙarfi ba. Tsaftar sinadarai, juriya ga harin sinadarai a zafin jiki, da riƙe ƙarfi a yanayin zafi ya sanya wannan abu ya shahara sosai kamar yadda wafer tray yana tallafawa da paddles a cikin tanderu na semiconductor. Thcell nameelectrical conduction kayan ya haifar da amfani da shi wajen juriya dumama abubuwa ga lantarki tanda, kuma a matsayin mabuɗin bangaren a thermistors (zazzabi resistors) da kuma a varistors (voltage m resistors). Sauran aikace-aikacen sun haɗa da fuskokin hatimi, faranti, bearings da bututun layi.
