【 摘 要 】

References(7)Cited-By(8)The crystallization behavior of hexanitrohexaazaisowurtzitane (HNIW) has been investigated at 298 K. Only the β form crystallized at the initial stage of crystallization, and it converted to the ε form with a solution-mediated transformation mechanism. Through the measurement of the solubilities of each polymorph (β and ε) at 298 K, it was confirmed that the ε form is stable and the β form is metastable. In addition, an analytical method has been developed for the determination of the fraction of the ε form in the precipitates using a FTIR spectrometer.
