Silicon Carbide Basic Properties:
-Ƙarancin yawa
- High thermal conductivity (kusa da aluminum)
-Kyakkyawan juriyar girgiza zafin zafi
-Tabbatar ruwa da gas
-High refractoriness (za a iya amfani da a 1450 ℃ a cikin iska da kuma 1800 ℃ a tsaka tsaki yanayi)
-Ba a shafe shi da lalata kuma kar a jika da narkakken aluminum ko narkar da zinc
-Babban taurin
- Low gogayya coefficient
-Abrasion juriya
-Ya tsayayya da asali kuma mai ƙarfi acid
- mai goge baki
-High inji ƙarfi
