| Abstract: | Dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (HATO) is a new generation of energetic material with low toxicity and high energy, which meet the needs of current weapon systems. To explore the effect of particle size on the thermal stability and thermal risks of HATO, decomposition reactions of HATO nanoparticles (NPs) and microparticles (MPs) were studied by accelerating rate calorimeter. The two decomposition stages for HATO NPs and HATO MPs were researched and the apparent activation energies were obtained with different reaction order. Furthermore, temperature at the time of no return and self-accelerating decomposition temperature of the two kinds of HATO were calculated and discussed. Moreover, the thermal behaviors of HATO NPs at atmospheric and high pressure were researched by differential scanning calorimetry. The decomposition of HATO NPs was more violent at high pressure with higher peak power and the related thermokinetic parameters at the pressure of 1.0 MPa were identified.
