Theoretical and experimental behavior of electrical breakdown of lead azide is discussed. Data indicate it is related to density and to sample thickness. Tests on samples saturated with various liquids indicate that breakdown is due to microdischarge in the pores and involves formation of electron traps. Initiation of detonation is said to be nonthermal, while its propagation is thermal, with sample density determining adequacy of heat transmission and, thus of propagation.
