High tsarki silicon carbide nika ciki yawa ganga kananan nauyi

(1) Babban ƙarfin injiniya, kamar yadda yake
Ƙarfin injina yana iya hana lalacewar kayan aiki yadda ya kamata, wanda yake da mahimmanci.Silicon carbide yana da ƙarfin injiniya mafi girma fiye da corundum.Misali, ƙarfin matsawa na silicon carbide shine 224MPa, yayin da na corundum shine kawai 75.7MPa.Ƙarfin lanƙwasawa na silicon carbide shine 15.5MPa, kuma na corundum shine 8.72MPa.

(2) High zafin jiki juriya, kananan coefficient na thermal fadada
Ana yin siliki carbide a yanayin zafi mai yawa.A 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 ℃.Ƙimar haɓakar haɓakar thermal na SIC ya fi ƙanƙanta fiye da na sauran kayan abrasives da kayan zafin jiki.Alal misali, ƙididdiga na thermal fadada corundum na iya zama babba kamar (7 ~ 8) × 10-6 / ℃.

(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.
