“…The large amounts of energy available on particle's surfaces during explosive compaction of powder mixtures permits shock wave synthesis of materials. The first observed chemical synthesis of this kind was that of the formation of zincferrite with its constituents [29] and shortly after that of T i c [30]. It was found that the amount of explosive necessary to initiate the chemical reaction is related to the reaction temperature under ordinary conditions [31, 321. Also exothermic reactions are possible under shock wave conditions.…”
