Farantin Ceramic na Alumina Mai Tsabta - don Rufewa da Kayan Zafi Mai Tsabta
An ƙera farantin yumbu na St.Cera daga alumina mai ƙarfi 99.8% (Al₂O₃), yana ba da ƙarfin dielectric mai yawa (15×10⁶ V/m), kwanciyar hankali na zafi har zuwa 1600°C, da kuma juriya mai kyau ga lalacewa. An yi wa faranti daidai gwargwado don cimma daidaiton ≤5 μm sama da 100 mm da kuma taurin saman Ra ≤0.4 μm. Akwai shi a cikin kauri na yau da kullun daga 1 mm zuwa 20 mm, girman da aka keɓance har zuwa 500 × 500 mm. Ana amfani da shi azaman masu hana wutar lantarki, tushen hita, layin ɗakin, da kuma abubuwan da aka yi amfani da su a cikin injin tsabtace iska.
