Posted May 11, 2004. Welcome to the forums. (shouldn't be saying this as I'm new myself, but anyway) Silicon dioxide is pretty inert and a hard chemical to split... you could react chlorine gas with it to liberate the oxygen, but you'd end up with liquid silicon tetrachloride (which explodes in water), and you'd have to find some way to deal ...Web
