WebApr 27, 2024 · Silicon was first isolated in 1824 by Swedish chemist Jöns Jacob Berzelius, who also discovered cerium, selenium and thorium, according to the Chemical Heritage Foundation. WebApr 11, 2024 · The temperature of quaternary eutectic reaction (Liquid→(Al)+(Si)+AlSc 2 Si 2 +Mg 2 Si) remains constant (558.22°C) in the Sc-additional Al-Si-Mg casting alloys, and the temperature surface is thus a plane. Moreover, with the increase of Si content, the fraction of primary (Al) decreases, and the fraction of ternary eutectic structure increases.
