Loaʻa i ka Silicon Carbide ke kūpaʻa maikaʻi loa i ka pala, ka ikaika mechanical kiʻekiʻe, ka conductivity thermal kiʻekiʻe, kahi coefficient haʻahaʻa loa o ka hoʻonui ʻana o ka thermal, a ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka haʻalulu thermal ma mua o nā mahana kiʻekiʻe loa o ka alumincell namet. Hana ʻia ka Silicon carbide me ka tetrahedra o ke kalapona a me nā ʻātoma silicon me nā pilina ikaika i loko o ka lattice kristal. Hoʻopuka kēia i kahi mea paʻakikī a ikaika loa. ʻAʻole hoʻouka ʻia ka Silicon carbide e kekahi waikawa a alkalis a i ʻole nā paʻakai heheʻe a hiki i 800ºC. I ka lewa, hana ʻo SiC i kahi uhi silicon oxide pale ma 1200ºC a hiki ke hoʻohana ʻia a hiki i 1600ºC. ʻO ke conductivity thermal kiʻekiʻe i hui pū ʻia me ka hoʻonui thermal haʻahaʻa a me ka ikaika kiʻekiʻe e hāʻawi i kēia mea i nā ʻano kūʻē haʻalulu thermal kūikawā. ʻO nā keramika Silicon carbide me ka liʻiliʻi a ʻaʻohe haumia palena palaoa e mālama i ko lākou ikaika i nā mahana kiʻekiʻe loa, e hoʻokokoke ana i 1600ºC me ka nalowale ʻole o ka ikaika. ʻO ka maʻemaʻe kemika, ke kūʻē ʻana i ka hoʻouka kemika i ka mahana, a me ka paʻa ʻana o ka ikaika i nā mahana kiʻekiʻe ua hoʻolilo i kēia mea i mea kaulana loa e like me ke kākoʻo wafer tray a me nā hoe i nā umu semiconductor. ʻO ka hoʻokele uila o ka mea i kapa ʻia ʻo Thcell ua alakaʻi i kona hoʻohana ʻia ʻana i nā mea hoʻomehana kū'ē no nā umu uila, a ma ke ʻano he ʻāpana koʻikoʻi i nā thermistors (nā resistors loli wela) a me nā varistors (nā resistors loli voltage). ʻO nā noi ʻē aʻe e pili ana i nā maka sila, nā papa ʻaʻahu, nā bearings a me nā paipu liner.
