Binary silicon-hydrogen compounds - Wikipedia

Binary silicon-hydrogen compounds are saturated chemical compounds with the empirical formula SiH n.All contain tetrahedral silicon and terminal hydrides. They only have Si–H and Si–Si single bonds. The bond lengths are 146.0 pm for a Si–H bond and 233 pm for a Si–Si bond. The structures of the silanes are analogues of the alkanes, starting with silane, SiH

Silane - Wikipedia

Silane is an inorganic compound with chemical formula, Si H 4, making it a group 14 hydride.It is a colourless, pyrophoric gas with a sharp, repulsive smell, somewhat similar to that of acetic acid. Silane is of practical interest as a precursor to elemental silicon. "Silanes" refers to many compounds with four substituents on silicon, including an organosilicon compound.

Silica | Minerals Education Coalition

Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
