  2. Silicon tetrachloride - Wikipedia

    en.wikipedia.org/wiki/Silicon_tetrachloride

    Si + 2 Cl 2SiCl 4. It was first prepared by Jöns Jakob Berzelius in 1823. [4] Brine can be contaminated with silica when the production of chlorine is a byproduct of a metal refining process from metal chloride ore. In rare occurrences, the silicon dioxide in silica is converted to silicon tetrachloride when the contaminated brine is ...
