Silicon SIC moldsilikiSSIC RBSIC m
Silicon carbide mara matsi (SSIC)Ana samar da ita ta amfani da foda mai kyau na SiC wanda ke dauke da additives sintering. Ana sarrafa shi ta hanyar yin amfani da hanyoyin da aka saba amfani da su don sauran yumbura kuma an yi su a 2,000 zuwa 2,200 ° C a cikin yanayin iskar gas mai ban sha'awa. Har ila yau, nau'in nau'i mai kyau, tare da nau'in hatsi <5 um, nau'i-nau'i masu girma tare da nau'in hatsi har zuwa 1.5. mm suna samuwa.
An bambanta SSIC da babban ƙarfi wanda ke dawwama kusan har zuwa yanayin zafi sosai (kimanin 1,600° C), yana riƙe da ƙarfin na dogon lokaci!
Amfanin samfur:
High zafin jiki oxidation juriya
Kyakkyawan juriya na lalata
Kyakkyawan juriya abrasion
High coefficient na zafi conductivity
Ƙaunar kai, ƙananan yawa
Babban taurin
Ƙirar ƙira.
