Abstract:
 
 
The high pressure behavior of Na3ONO2 has been investigated by Raman spectroscopy and angle-dispersive X-ray diffraction from synchrotron radiation by using the diamond anvil cell technique. Pressure induced phase transitions and finally amorphization are observed. Starting from cubic symmetry at ambient conditions Na3ONO2 transforms to a rhombohedral high pressure phase at 0.7 GPa. Beyond 14.1 GPa, the crystalline structure destabilizes and amorphous state is achieved.
