Abstract

The negative pressure (tension) was measured by Raman spectroscopy in an aqueous 2m Na2WO4–CsCl solution during a metastable-to-stable state transition. Phase transitions were observed optically in synthetic fluid inclusions in a single quartz crystal. In the metastable liquid phase, the vapor phase nucleation pressure at 48°C is −105 ± 5 MPa. Water equation of state (IAPWS-95) predicts the nucleation pressure for this density to be approximately −160 MPa.
