Abstract
In the present study, heat of combustion (ΔHc) values are calculated for energetic materials (EM's) pellets based on ammonium perchlorate (AP), ammonium dinitramide (ADN) and potassium dinitramide (KDN) using a bomb calorimeter unit. ADN, KDN, and AP were mixed with carbon black (CB) in various ratios for preparing EM's pellets. Two set of experiments were performed for evaluating ΔHc for prepared pellets. In the first set of experimentation, pellets made from the mixtures of ADN, AP, and CB in different ratios were used, while in the second set of experimentation, pellets made from the mixtures of KDN, AP, and CB in different ratios were used. In all the formulations, CB acts as an organic fuel and as a catalyst, while the AP, ADN, and KDN act as oxidizer entities. The pellets were prepared using a pellet maker provided with the bomb calorimeter unit. It was observed that pure ADN/CB pellet did not burn, while pure KDN/CB pellet did not burn. Further, pure AP/CB pellet produces the highest ΔHc as compared to other prepared EM pellets.
