含能共晶材料是含能材料领域的研究热点。对于低感度高能材料，通过理论计算，研究了41种二元含能共晶的密度（d）、氧平衡（OB）、爆炸性能和晶体形貌，评价了它们的威力和安全性。结果表明：与高能纯组分相比，共结晶后的能量被稀释，但安全性可能得到改善;共结晶介导组成纯组分的OB，以及有时例外的d，并且它可以改变相对于所涉及的纯高能组分的晶体形状。对这些共晶进行了定性甚至定量的修正，验证了影响功率和安全性的因素，得出了d和OB的一些指标（当VD ≥ 8.5 km s-1和H50 ≥ 50 cm时，d298 K ≥ 1.78 g cm-3和−100% ≤ OB ≤ −50%），以及低灵敏度高能共晶的设计方法和建议。
Energetic cocrystals are attracting increasing attention in the field of energetic materials. To low-sensitive and high energetic materials, we provide the evaluations of power and safety of 41 observed binary energetic cocrystals, by studying their densities (d), oxygen balances (OB), explosive properties and crystal morphologies with the aid of theoretical calculations. The results show that: the power is diluted but the safety may be improved after cocrystallization in contrast to the more energetic pure component; the cocrystallization mediates the OB of the composing pure components, as well as d with some exceptions sometimes, and it can alter crystal shapes relative to pure energetic components involved. Some qualitative even quantitative corrections of these cocrystals are obtained to verify the factors influencing the power and the safety, leading to some specifications of d and OB (d298K ≥ 1.78 g cm−3 and −100% ≤ OB ≤ −50% regarding VD ≥ 8.5 km s−1 and H50 ≥ 50 cm), a procedure and some suggestions for designing low sensitive high energetic cocrystals.
