Abstract:
Using the diamond anvil cell technique, angle-dispersive X-ray
diffraction and Raman spectroscopy were employed to study the
high pressure behavior of mercury cyanamide. Its decomposition
under pressure starts at 1.9 GPa and is not completed even up
to 10 GPa. The decomposition product alpha-Hg transforms to
beta-Hg during 7-10 GPa, while the ON residual is not
detectable by X-ray diffraction. The zero pressure bulk modulus
of mercury cyanamide is estimated as 38.5 GPa.
