Sažetak
Thermal methods play important role among various measuring techniques 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 application of isothermal and non-isothermal thermogravimetry for determination of nitroglycerine content in double based propellants. It has been found out that thermogravimetry can be used not only to distinguish clearly between nitrocellulose and double based propellants, but also for rough determination of nitroglycerine content in double based propellants. The difference between an actual and experimentally determined content of nitroglycerine in double based propellants (i.e. accuracy of the method) is dependent on composition of propellant and data treatment method.
