Phys. Rev. Lett. 52, 1312–1314 (1984)New High-Pressure Phase of H2O: Ice XReceived 7 October 1983; published in the issue dated 9 April 1984 H2O at 300 K has been studied up to 67 GPa by Brillouin scattering. A transition to a new form of ice occurs at 44 GPa. This is the tenth known solid form of H2O and may be the expected "symmetric-ice" structure. © 1984 The American Physical Society URL:
