“…At the same time, the introduction of ether bonds significantly increase the molecular flexibility, providing the compounds with plastic strength and low sensitivity, combined with energy, safety and mechanical properties. One of these compounds, bifurazano [3,4-b: 3 ,4 -f] furoxano [3 ,4 -d]oxacycloheptatriene (BFFO), with two furazan and one furoxan cycles fused into the oxacycloheptane ring, is expected to be an excellent melt-cast carrier explosive [20][21][22]. Its molecular structure is shown as Figure 1 and the energy properties are listed in Table 1 [23].…”

A novel energetic material, Bifurazano [3,4-b: 3′,4′-f] furoxano [3″,4″-d] oxacyclo-heptatriene (BFFO), has been investigated regarding two aspects, namely its thermal decomposition and solidification characteristics. The DSC curves indicate that the peak temperature of BFFO decomposition process is 271.1 °C under the static pressure of 2 MPa and the volatility of BFFO at 120 °C is significantly lower than that of TNT, DNAN and DNTF. The solidification curve indicates that the solidification of BFFO is a basic linear uniform solidification process, which is obviously different from that of TNT, DNAN and DNTF. In addition, the facet of BFFO appears much smoother and fewer defects are observed in the solidified body after solidification via CT and SEM. The reduction in solidification defects also further improves the mechanical properties of BFFO, with significant improvements in compressive and tensile strength compared to DNTF, DNAN and TNT. In summary, BFFO is a potential melt-cast carrier explosive with excellent thermal stability, solidification characteristics and mechanical properties.
