Summary
Both crystalline and colloidal lead azide were treated in dry carbon dioxide gas, wet carbon dioxide gas, and in a mixture of water vapor and an inert carrier gas, at various water vapor pressures and temperatures near and above normal storage conditions. The formation of surface compounds was followed by electron micrographs taken at intervals during crystal treatment. The final surface products formed by this treatment were identified by infrared spectroscopy. It was determined that dry carbon dioxide had little effect on lead azide. However, water reacted readily with lead azide forming a basic lead azide, which in turn reacted with carbon dioxide to produce carbonates on the crystal surfaces. These carbonates were observed to form on lead azide under conditions approximating ambient storage conditions. Surface impurities thus formed may be expected to affect the initiation reliability of lead azide. Hence water does not appear to be an ideal storage environment for lead azide. (auth)
