WebIt generally occurs following the reaction: X ∙ X 2 2 ∙ S i H X 3 + O X 2 S i ( O) O H + H + H but the intermediates change depending on temperature and the energetics of the reaction. You can find more information in a couple of papers: Babushok, Tsang, Burgess Jr., Zachariah, "Numerical study of low- and high-temperature silane combustion." Web1. Hydroxyl radicals (OH) clean the air. Image: Elmar Uherek. Oxidation in a chemical sense does not necessarily mean a reaction with oxygen containing compounds, it is rather the loss of electrons. However, in the air, oxidation does generally involve the reaction of a chemical species with an oxygen containing compound.
