Relevant to the self-propagating high-temperature synthesis (SHS) process, an analytical study has been conducted to investigate\r\nthe effects of electric field on the combustion behavior because the electric field is indispensable for systems with weak exothermic\r\nreactions to sustain flame propagation. In the present study, use has been made of the heterogeneous theory which can satisfactorily\r\naccount for the premixed mode of the bulk flame propagation supported by the nonpremixed mode of particle consumption. It has\r\nbeen confirmed that, even for the SHS flame propagation under electric field, being well recognized to be facilitated, there exists\r\na limit of flammability, due to heat loss, as is the case for the usual SHS flame propagation. Since the heat loss is closely related to\r\nthe representative sizes of particles and compacted specimen, this identification provides useful insight into manipulating the SHS\r\nflame propagation under electric field, by presenting appropriate combinations of those sizes. A fair degree of agreement has been\r\ndemonstrated through conducting an experimental comparison, as far as the trend and the approximate magnitude are concerned,\r\nsuggesting that an essential feature has been captured by the present study.
