Abstract

Explosives are used in both military and civilian applications all over the world. Sufficient longevity and good thermal stability are therefore essential for safe handling and safe storage of energetic materials. In this work, five well-known compounds, TKX-50, RDX, HMX, CL-20 and PETN, were investigated by means of different kinetic models, in order to make predictions about their long-term stability. For this purpose, the compounds were synthesized according to literature-known procedures and thermogravimetric (TG) measurements were performed. The TG plots were analyzed using the Ozawa-Flynn-Wall, Friedman and ASTM E698 kinetic models with the NETZSCH Kinetics Neo software and the activation energy and isothermal long-term stability were determined. Moreover, various climatic predictions of different countries were made.
