摘要: The equation of state and the unit cell parameters triamino-trinitrobenzene (TATB) have been measured up to 66 GPa by x-ray diffraction on multi-grain samples. A custom indexing pattern was implemented enable an unambiguous assignment peaks. structural data reveal a more isotropic response compression above 10 GPa, indicating that van der Waals forces are no dominant interplanar interactions. compared with density functional theory calculations, including empirical D2 correction for An excellent agreement is obtained 20 GPa increasing deviation above. present determination TATB isothermal reliable detonation physics applications.
