Analytical application of thermal methods in the field of explosive materials

Thermal methods play important role among various measuring techniques used in the analysis of explosive materials. Although these methods are usually applied for the characterisation and determination of the thermal properties of an explosive (e.g. melting process, polymorphic transformations, thermal stability, kinetics of thermal decomposition, temperature of initiation, etc.), they can be also used for analytical purposes. Herein we present the possibilities of applying differential scanning calorimetry (DSC) and thermogravimetry (TGA) for both qualitative and quantitative analysis. We show that these methods may be used for the identification of several standard high explosives and their mixtures, for the determination of the purity and quality of an explosive, for the identification and determination of the content of phlegmatiser and for the analysis of the multi-component systems. The small sample size, the sample heterogeneity, the dynamic character of the processes taking place during measurements may all affect the outcome of the quantitative measurements, whereby some of the thermal methods may eventually appear less suitable for precise quantitative analysis.
