It has been found that for the two-step spontaneous combustion of silane with oxygen in an enclosed space when heterogeneous chain breaking occurs, the first flash occurs at the walls of the reactor, and the second within the reaction volume. It has been shown that the preliminary partial removal of the adsorbed intermediate reaction products reduces the intensity of the first flash of the pulsed combustion, evidence of the important role of the components adsorbed on the surface in chain branching.
