The crystallization behavior of hexanitrohexaazaisowurtzitane (HNIW) has been investigated at 298 K. Only the <I>β</I> form crystallized at the initial stage of crystallization, and it converted to the <I>ε</I> form with a solution-mediated transformation mechanism. Through the measurement of the solubilities of each polymorph (<I>β</I> and <I>ε</I>) at 298 K, it was confirmed that the <I>ε</I> form is stable and the <I>β</I> form is metastable. In addition, an analytical method has been developed for the determination of the fraction of the <I>ε</I> form in the precipitates using a FTIR spectrometer.
