Stability Testing of Energetic Materials by Isothermal Microcalorimetry
Overview
This webinar introduces the use of isothermal microcalorimetry for stability measurement of energetic materials. Energetic materials refer to materials, chemicals and substances which exhibit a risk for self-decomposition associated with self-heating ultimately resulting in run-way reactions. Such materials include propellants, percarbonates and peroxides, and these need to be evaluated to ensure safe conditions for handling, transport and storage.
Microcalorimetry is a suitable tool to monitor the rate of heat production of energetic materials under safe conditions. Only small quantities of sample are needed and the results can be used for prediction of runaway reactions and to predict safe storage conditions. With microcalorimetry the critical parameter for this determination – the rate of heat production, is measured.
With microcalorimetry the decomposition and stability evaluation can be made on the material itself but it can also be used to evaluate compatibility and possible interactions with other materials.
A brief theory as well as examples of measurements on percarbonates and propellants will be given. The measurement procedure and evaluation using STANAG 4582 will also be reviewed during the webinar.
