Dehydration and lattice volume change of hydrous SiO2 stishovite

Caption

Change of lattice volume during heating to 1300ºC at 23 GPa. Hydrous stishovite crystalized at 500ºC showed large lattice volume, whereas the lattice volume after dehydration by subsequent heating was close to that of the anhydrous state.
