SURFACE RATE PROCESSES AND SENSITIVITY OF HIGH EXPLOSIVES,
Abstract
The nature and rate of linear surface regression of TNT, RDX, tetryl and PETN were studied utilizing a hot plate pyrolysis technique over surface temperatures ranging as high as 500C. The data, when compared to similar data for benzoic acid, suggest that the primary surface rate process appears to be an endothermic meltflow having an apparent activation energy suggestive of heat transfer and viscous flow as a rate controlling step. These data, when used as a measure of surface heat dissipation, correlate very well with the measured values of impact sensitivity. Also, they offer an explanation for the fact that attempts to correlate impact and/or friction sensitivity with melting point alone could lead to misleading results when PETN and RDX are considered.
