It's 70% amorphous silicone dioxide.

It describes the metabolism from hydrogen sulphide into silicon dioxide.

Silicon dioxide. The waste product of a silicon-based organism.

The solution was to use Aerogel... a fragile, porous substance made from silicon dioxide.

e. Substrates of silicon-on-insulator (SOI) for integrated circuits in which the insulator is silicon dioxide;

(a) Fire decomposition products A wide variety of decomposition products are generated during the process of combustion, including (see footnote 24): Ash (typically containing carbon, zinc oxide, titanium dioxide, silicon dioxides, cadmium, lead, and other heavy metals); Sulphur compounds; Polynuclear aromatic hydrocarbons; Aromatic oils; Carbon and nitrogen oxides; Particulates; and Various light-end aromatic hydrocarbons (such as toluene, xylene, benzene, etc).
