摘要: Two experiments are reported on KClO 4 at extreme conditions. A static high pressure Raman study was first conducted to 18.9 GPa. Evidence for at least two new phases was observed: one between 2.4 and 7.7 GPa (possibly sluggish), and the second near 11.7 GPa. Then, the X-ray induced decomposition rate of potassium perchlorate KClO 4→ h ν KCl+ 2 O 2 was studied up to 15.2 GPa. The time-dependent growth of KCl and O 2 was monitored. The decomposition rate slowed at higher pressures. We present the first direct evidence for …
