Ammonium nitrate (AN) extensively used as an oxidizer in energetic compositions is a promising compound as a propellant and gas generator. It is well known that metal oxides help to address some of the disadvantages of AN, such as the low stability and low burning rate. To investigate the effect of nickel oxide (II) (NiO) on thermal decomposition of AN mixtures, the thermal characteristics of AN, activated carbon C, and NiO mixtures as of metal–organic frameworks (MOFs) were measured using simultaneous differential scanning calorimetry. The compositions were burnt at the pressures 1, 2, 3, and 3.5 MPa in a combustion chamber, and the burning rates were determined. On addition of a metal oxide, the burning rate was shown to increase three–four times. Besides, the activation energy of the systems was calculated.
