On fundamental morphology of benzophenone crystal

This paper presents the constant temperature melt method to study the fundamental morphology (FM) of benzophenone crystal. The main conclusions are as follows: (1) The lattice energy of benzophenone crystal calculated with the Lennard-Jones 12-6-1 potential function is 105.6kJ/mol, which agrees very well with the experimental result of 102.4kJ/mol. (2) The crystal morphology of benzophenone grown by constant temperature melt method is consistent with the numerical results obtained after intricate calculations on the basis of E_8,hkl criterion. This shows that F.M. is obtained with certainty. (3) The small distinction of {111} face size between the results of experiment and theoretical calculation is due to the adsorption of inclusions. (4) Within the range of 0.2°C-1.0°C, the undercooling has little influence on the crystal morphology.
