Silane
Silane (SiH4), also called silicon tetrahydride, is a colorless, pyrophoric gas and the silicon analog of methane that ignites spontaneously in air; it is a key precursor for semiconductor and solar-cell silicon.
Silane coupling agents
Silane coupling agents are organofunctional silanes, typically X–CH₂CH₂CH₂–Si(OR)₃, that bond inorganic surfaces such as glass, silica, and metal oxides to organic polymers, improving adhesion in composites.
Silanes and siloxanes
Silanes are saturated silicon hydrides, analogs of the alkanes with formula SinH2n+2, while siloxanes are compounds with alternating silicon and oxygen frameworks that lead to silicones.
