In industrial glass: From the gaseous state
…making of silica glass by hydroxylation. In the hydroxylation technique, vapours of silicon tetrachloride (SiCl₄) are reacted at high temperatures with steam (H₂O), causing a “soot” of silica (SiO₂) to deposit on cooler substrates. The soot is subsequently sintered to a dense glass. (A practical application of this technique involving…
