The delay time of a column of pyrotechnic material when used in a delayed action electric detonator is defined as the time between the application of the initiating electrical impulse and the detonation of the explosive charge of the detonator. The effects of fuel/oxidant ratio and fuel surface area on the delay time have been measured for the silicon/red lead system. From the data obtained it has been possible to identify a possible reaction mechanism for this pyrotechnic composition.
