IMPACT SENSITIVITY OF LEAD AZIDE IN VARIOUS LIQUIDS WITH DIFFERENT DEGREES OF CONFINEMENT

Abstract

The work described in this report was conducted to determine the sensitivity of unconfined mixtures of lead azide with various liquids as measured with an impact machine. The test was developed by so modifying the standard Picatinny Arsenal impact test that the confinement of the sample was reduced; a well was introduced to retain the sample in relatively large amounts of liquid during impact. The results indicate that dry, unconfined lead azide is initiated by impact at lower drop heights than the same material confined in the standard impact-test fixture. The reason for this apparent increase in impact sensitivity is not clear; it may be attributed to some uncontrolled experimental parameter. Unconfined mixtures of lead azide and water, lead azide and alcohol, lead azide and water-alcohol, and lead azide and Freon TF were found to be less sensitive to impact than dry lead azide.
