Silicon monoxide is the chemical compound with the formula SiO where silicon is present in the oxidation state +2. In the vapour phase, it is a diatomic molecule. [ 1 ] It has been detected in stellar objects [ 2 ] and has been described as the most common oxide of silicon in the universe.
[15] [16] Above 420 °C (788 °F), silane decomposes into silicon and hydrogen; it can therefore be used in the chemical vapor deposition of silicon. The Si–H bond strength is around 384 kJ/mol, which is about 20% weaker than the H–H bond in H 2. Consequently, compounds containing Si–H bonds are much more reactive than is H 2.

A product comprising a few repeat units (n = 1 to 2) is a viscous, clear liquid; this is called a liquid epoxy resin. A product comprising more repeating units ( n = 2 to 30) is at room temperature a colourless solid, which is correspondingly referred to as solid epoxy resin.
A silicone oil is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane . These polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties.
In organosilicon chemistry, a siloxane is an organic compound containing a functional group of two silicon atoms bound to an oxygen atom: Si−O−Si. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H[OSiH 2 ] n OH and [OSiH 2 ] n . [ 1 ]
