Observation of hexagonal close-packed water ice at conditions in ice giant planetary interiors
Alexis Forestier, Gunnar Weck, Sandra Ninet +4
Using synchrotron x-ray diffraction in laser-heated diamond anvil cells, we report the observation of an hexagonal close-packed (hcp) phase of water ice at high pressure and temper…
High pressure-temperature phase diagram of ammonia hemihydrate
L. Andriambariarijaona, F. Datchi H. Zhang, K. Béneut +3
We report a comprehensive experimental investigation of the phase diagram of ammonia hemihydrate (AHH) in the range of 2-30 GPa and 300-700 K, based on Raman spectroscopy and x-ray…
Metallization of Shock-Compressed Liquid Ammonia
A. Ravasio, M. Bethkenhagen, J. -A. Hernandez +8
Ammonia is predicted to be one of the major components in the depths of the ice giant planets Uranus and Neptune. Their dynamics, evolution, and interior structure are insufficient…
Ionic ammonia ice
S. Ninet, F. Datchi, P. Dumas +6
We report experimental and theoretical evidence that solid molecular ammonia becomes unstable at room temperature and high pressures and transforms into an ionic crystalline form.…
High pressure-high temperature phase diagram of ammonia
Sandra Ninet, Frédéric Datchi
The high pressure(P)-high temperature(T) phase diagram of solid ammonia has been investigated using diamond anvil cell and resistive heating techniques. The III-IV transition line…
