Zoben Mai Da Hankali na Semiconductor na ST.CERA na musamman
An yi shi da tsarkakken ƙarfe mai ƙarfi (sama da 99.5%) na alumina, wanda aka yi shi ta hanyar matsewa mai sanyi da kuma niƙa a ƙarƙashin zafin jiki mai yawa, sannan a yi masa injin daidai kuma a goge shi, kayan gyaran ƙarfe na yumbu na iya biyan duk wani ƙa'ida mai tsauri na kayan aikin semiconductor tare da fasalulluka na juriyar lalacewa, juriyar tsatsa, ƙarancin faɗaɗa zafi, da kuma rufin rufi.
Tare da fasalulluka na juriyar zafin jiki mai yawa, juriyar tsatsa, juriyar abrasion da kuma rufin rufi, yumbu na iya aiki a cikin nau'ikan kayan aikin samar da semiconductor iri-iri tare da yanayin zafi mai yawa, injin iska ko iskar gas mai lalata na dogon lokaci.
An yi shi da foda mai tsabta na alumina, wanda aka sarrafa ta hanyar matsi mai sanyi, sintering mai zafi da kammalawa daidai, zai iya kaiwa ga juriyar girma zuwa ±0.001 mm, kammala saman Ra 0.1, juriyar zafin jiki 1600℃.
