Abstract

ABSTRACT The energetic characteristics of a novel ionic cocrystal composed of 1H-tetrazole/sodium perchlorate and differences of properties between the cocrystal and simple mixture are reported herein. Cocrystals containing reductants and oxidizers exhibit enhanced energy release rate compared with their simple mixture owing to their short molecular distances. Differential scanning calorimetry, thermogravimetric analysis, sensitivity tests and humidity tests are performed to clarify the properties of the cocrystals and simple mixture. The calculated detonation velocity of the cocrystal was higher than that of 1H-tetrazole. The cocrystal achieves high deflagration performance, as evaluated via a pressure vessel test.
