Siab cov khoom siv Silicon Hlau
Cov khoom lag luam
Silicon Hlau Muaj lub ntsiab lus siab, muaj zog, thiab oxidation tsis kam thiab corrosion tsis kam thiab corrosion tsis kam, cov khoom siv kub heev-kub. Txawm li cas los xij, nws brittleness tau dhau los ua qhov teeb meem tseem ceeb tau ua cov ntawv thov kev lag luam, uas yog feem ntau txiav txim siab los ntawm theem muaj pes tsawg leeg thiab microstructure ntawm cov khoom. Kev sib sau ua ke thiab sib xyaw ua ke tuaj yeem txhim kho microstructively txhim kho microstructure thiab kev ua tau zoo ntawm nws yog xim hlau Silicides.
