High zafin jiki juriya sa juriya high taurin silicon carbide nika drum za a iya musamman

(1) Babban juriya na zafin jiki, ƙananan haɓakar haɓakar thermal
Ana yin siliki carbide a yanayin zafi mai yawa.A cikin wasu yanayin zafi mai zafi, ana buƙatar kayan don samun takamaiman ƙarfin aiki, da saduwa da daidaiton aiki, kuma yumbu na silicon carbide na iya cimma waɗannan maki biyu.Mafi girman zafin jiki na silicon carbide yana da kusan 800 ℃, kuma yanayin zafin ƙarfe na ƙarfe shine kawai 250 ℃.Ta m lissafi, matsakaicin thermal fadada coefficient na SIC ne 4.4 × 10-6 / C a cikin kewayon 25 ~ 1400 ℃.Matsakaicin haɓakar haɓakar thermal na SIC ya fi na sauran abubuwan abrasives da kayan zafi mai girma.Alal misali, da coefficient na thermal fadada corundum iya zama kamar yadda (7 ~ 8) × 10-6 / ℃.

(2) High thermal conductivity
Babban haɓakar thermal conductivity na SIC wani muhimmin sifa ne na kayan jikinsa.Thermal conductivity na silicon carbide ya fi na sauran refractory kayan da abrasives, game da 4 sau na corundum.Silicon carbide thermal fadada coefficient ne low, high thermal watsin, yin kayayyakin sa a cikin aiwatar da dumama da sanyaya a karkashin m thermal danniya, wanda kuma silicon carbide kayayyakin thermal girgiza juriya ne musamman kyakkyawan dalili.

(3) Juriya na lalata
Silicon carbide saboda narke batu (ruwan zafin jiki), sinadaran inertia da thermal girgiza juriya ne high, za a iya amfani da iri-iri na silicon carbide yumbu kayayyakin, kamar yumbu kayayyakin makera nika kayan aikin, rufi farantin da sagger, zinc smelting masana'antu a tsaye. Silinda distillation makera tare da silicon carbide tubali, aluminum electrolytic cell rufi, crucible, kananan tanderun abu.
