| الوصف: | Solid−solid−liquid transitions of DKDP were studied as a function of temperature along the 0.7 GPa isobar. Raman spectra of DKDP were collected at incrementally higher temperatures up to the melting transition. At higher temperatures, the PO4 symmetric vibrational mode shifted to higher energy, which is indicative of deuterium loss, and broadened, which is indicative of deformation of the PO4 tetrahedron. Prior to melting, DKDP began to decompose to potassium oligophosphate material. Upon a return to ambient conditions, the material recovered from the melted regions contained DKDP and KDP as well as KPO3. These results suggest that the thermal treatment of DKDP at high pressure can result in the decomposition of DKDP. |
