This paper studies the effects of cerezin and mixture of cerezin with stearin as a phlegmatizer whit total content varies from 5% to 8%, to thermal decomposition of TΓAΦ in comparision with TΓA and pure explosives. The results show that melting point of TNT in both TΓA and TΓAΦ changed insignificantly. | The effect of phlegmatizers to the thermal decomposition of the composite explosive
