Abstract: The safety problems of production and exploitation of powerful melt-cast composite explosives require the replacement of the conventional fusible binders—trotyl and dinitrazapentane—by less sensitive high-energy materials. Insensitive derivatives of 3-nitro-1,2,4-triazole (1-,2-methyl, tert-butyl-, ethoxymethyl-) and their eutectic melts with bisnitrofurazanyl furoxane can be employed as such additives. Explosive composites containing HMX, hexanitrohexaazaisowurtzitane, nitrotriazolone, triaminotrinitrobenzene, and fusible additives based on nitrotriazolone derivatives were characterized herein by differential scanning calorimetry (DSC). For composite explosive systems based on HMX, the optimum options were ethoxymethyl-3-nitro-1,2,4-triazole and its eutectic melt with bisnitrofurazanyl furoxane (80/20 ratio), whereas for composite explosives based on hexanitrohexaazaisowurtzitane, the optimum option was 1-methyl-3-nitro-1,2,4-triazole and its eutectic mixture with bisnitrofurazanyl furoxane (80/20 ratio).
