含能低共熔物熔铸载体炸药的研究进展OA

Melt-cast carrier explosives are fundamental low-melting-point constituents for melt-cast explosive formulations,and their properties are critical to the engineering practicability of melt-cast explosives.To address the inherent drawbacks of the tra-ditional melt-cast carrier explosive 2,4,6-trinitrotoluene(TNT),energetic eutectic mixtures have emerged as a popular research focus,benefiting from their tunable thermochemical properties,energy and safety performances.Methods for constructing T-X and H-X phase diagrams of energetic eutectic mixtures are elaborated,alongside approaches to determine their compositions,melting points and phase distribution rules.Additionally,the state-of-the-art studies on energetic eutectic mixtures based on 1,3,3-trinitroazetidine(TNAZ),3,4-dinitrofurzanfuroxan(DNTF),1-methyl-3,4,5-trinitropyrazole(MTNP)are discussed.On the basis of current research situation,the development potential and core research directions of energetic eutectic mixtures are pro-posed.This work intends to facilitate the design and formula optimization of novel low-sensitivity,high-energy melt-cast explo-sives.
