Sažetak
Thermal methods play important role among various measuring technique used in the analysis of explosive materials. These methods are mostly used for the investigation and determination of thermal properties of energetic materials (e.g. melting process, polymorphic transformations, temperature of initiation, etc.), as well as to estimate thermal stability, and to study thermal decomposition. Furthermore, thermal methods can be also used for analytical purposes, such as identification of some commonly used high explosives, determination of their purity, determination of phlegmatiser content, etc. The aim of this work was to study the possibility of isothermal and non-isothermal thermogravimetry (TGA) application for identification of the homogeneous propellants type, and to determine nitroglycerine content in double based propellants. It has been found out from the shapes of TGA thermograms, i.e. from the position of some characteristic points on the theromograms that it is possible to distinguish clearly between nitrocellulose and double based propellants. Furthermore, from the isothermal and non isothermal TGA thermograms, nitroglycerine content in double based propellants could be roughly determined (with an error less than 5%).
