Abstract
AbstractExploration of novel energetic‐energetic co‐crystals has greatly increased in recent years as the need for energetic materials with improved detonation performance and reduced sensitivity continues to grow. In 2015 a CL‐20/TATB co‐crystal was reported and touted sensitivity and detonation properties that would make it a potential replacement for the industry standard HMX. The confirmation, reproducibility, and characterization of energetic materials are still a widely debated topic especially when the material of interest has exceptional properties. In this work, CL‐20/TATB co‐crystals are attempted via solvent‐nonsolvent (S/NS) cocrystallization to assess the formation of a true co‐crystal. The prepared crystals were characterized via scanning electron microscopy (SEM), powder x‐ray diffraction (PXRD), fourier transform infrared spectroscopy (FTIR), raman spectroscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). This work reproduced S/NS cocrystallization similar to that reported in 2015, provides a solubility and thermodynamic explanation behind CL‐20/TATB cocrystallization, and assesses the future viability of CL‐20/TATB crystals.
