Abstract : A study was made at the Department of Thermal Physics of the Leningrad Polytechnical Institute to analytically determine the conditions under which the combustion process which develops on the surface of a metal particle results in the ignition of the metal vapors, i.e., the transition from surface- to vapor-phase burning. It was shown that any magnesium particle heterogeneously ignited will burn in the vapor phase. It was also shown that the analytical analysis applied only to those cases where the oxide layer on the particle surface does not considerably affect the transfer of heat and the reactants. (Author)
