Phaj Alumina Ceramic Uas Muaj Peev Xwm Siab - rau Kev Rwb Thaiv Tsev & Cov Khoom Siv Kub Siab
Cov phaj ceramic ntawm St.Cera yog tsim los ntawm 99.8% alumina uas muaj purity siab (Al₂O₃), muaj zog dielectric siab (15 × 10⁶ V/m), ruaj khov thermal txog li 1600°C, thiab tiv taus kev hnav zoo heev. Cov phaj raug lapped kom ua tiav qhov tiaj tiaj ≤5 μm dhau 100 hli thiab qhov roughness ntawm qhov chaw Ra ≤0.4 μm. Muaj cov tuab txheem txij li 1 hli txog 20 hli, qhov loj me tshwj xeeb txog li 500 × 500 hli. Siv ua cov insulators hluav taws xob, cov hauv paus cua sov, cov ntaub thaiv chamber, thiab cov khoom siv nqus tsev vacuum chuck.
