A mechanism of low temperature silane combustion has been proposed in the p
resent work based on the assumption that a trace amount of water vapor help
s the occurrence of spontaneous ignition at room temperature. This assumpti
on has been made based upon the fact that the combustion product of silane
influences positively the occurrence of spontaneous ignition. Energetic cal
culation of the reaction path way for low temperature silane combustion als
o supports this assumption [Kondo et al., 1999]. A numerical model has been
constructed which can interpret the spontaneous ignition limit at room tem
perature, the ignition delay times, and the second explosion limit of silan
e mixtures simultaneously.
