Influence of Oxygen Balance on Explosive Properties

The liquid explosive, with zero or near zero oxygen balance, has relatively large detonation strength and detonation intensity [3-5]. In Table 3.2, a set of oxygen balance, detonation strength, and detonation intensity test data of nitric acid-toluene liquid explosive mixture was listed. The experiment results showed that nitric acid-toluene liquid explosive mixture, when the composition was close to zero oxygen balance, had relatively high explosive property while, had relatively low explosive 

Fedorov et al. [6] had studied explosive properties of tetranitromethane and nitrobenzene explosive mixture with different proportions in detail. The experiment results were listed in Table 3.3. 

Because the lead column in Table 3.3 was not be calibrated, some of the test data might be too large, but they still could be compared relatively. When the liquid explosive had 22.5 % of nitrobenzene, explosion velocity and strength were the most powerful when nitrobenzene was 20-25 % (oxygen balance was 6.68 to -3.9 %), its explosion velocity and strength were located within the high value area.

According to the impact of oxygen balance of explosive on its explosion strength, the principle of zero oxygen balance should be usually followed during the formulation design of liquid explosive.
