Abstract : Experiments on the thermal decomposition of lead azide in vacuum and various atmospheres consisting of or containing air, oxygen, nitrogen, water or iodine vapor are described. Gases which are capable of reacting with the lead nuclei formed during the decomposition have the effect of increasing the induction period of the autocatalytic reaction or even suppressing this type of reaction completely. In the presence of water vapor a hydrolysis reaction mechanism. Iodine vapor not only affects the lead nuclei, but also the azide group. On the other hand the thermal decomposition of lead azide is enhanced by the addition of silver. Similar environmental effects are observed when lead azide is detonated in air, vacuum or in admixture with silver. (Author)
