Abstract Chemical igniters are used in the study of dispersed dusts. Energy released during their use is defined by EN 14034 at 2 x 5 kJ. The Standard does not define the exact composition of the pyrotechnic mixture. The condition of using the igniter is to release energy according to the Standard. This article is focused on pyrotechnic composition with magnesium powder. It deals with various ways of activating, preparing and sealing the pyrotechnic mixture in the igniter. These values are important for setting up a device for studying the explosive properties of dispersed dusts.

pyrotechnic mixtures are sensitivity with the influence of humidity and are susceptible to explosive decompositions. The aim of this paper is to provide thermal decomposition data under different humidity conditions. The method of TG-DSC simultaneous analysis has been used to study the thermal decomposition mechanism of a typical red pyrotechnic mixture. The kinetic parameters were calculated by kissinger method. The thermal stability is evaluated by decomposition peak temperature (Tm), mass loss (△m) and activation energy (E), which shows that the decomposition peak temperature and activation energy decreased obviously. Therefore, the thermal safety under humidity atmosphere become lower.
