Abstract

It is hard to measure the crystalline heat of CL-20 accurately, not only due to the instrument precision, but also β-polymorph transforming to ε-polymorph can be found easily and frequently in the crystallization progress. This work presents a study of experiments to clarify the crystallization model of ε-CL-20 and α-CL-20 using a solvent/antisolvent method by microcalorimetry without β-polymorph appearing. The results show that the crystallization progresses of ε-CL-20 and α-CL-20 are exothermic and they are fit the theory of Burton-Cabrera-Frank dislocation theory．
