Thermal Conductivity Measurement of Explosives, Energetics and Pyrotechnics
Testing the thermal conductivity of most energetic materials is a challenge with traditional steady-state techniques, as the required large volumes of material pose undesirable safety risks or the necessary sample geometries are impractical. This often leads to estimation of thermal conductivity in predictive models rather than actual measurement. The dependence of thermal conductivity of a material undergoing an exothermic reaction on local temperature has a significant effect on the critical conditions for thermal ignition.
 The TCi's modified transient plane source technique (MTPS) offers the unique capability to measure the thermal conductivity of an energetic material directly as an alternative to the book values that are frequently substituted in the computational models. The MTPS requires minimal volumes of material, utilizes extremely short testing time parameters (0.8 second) and employs a low energy measurement pulse that makes it the optimal solution in the characterization of energetics.
