“…Our results can be compared to previous work. For ethanol, we display the largest negative P cav reached at two temperatures in repeated runs in a metallic Berthelot tube: they are less negative than the one obtained with the SPM in the acoustic experiment. Vinogradov and Pavlov measured P cav in ethanol and heptane using a heat pulse on a thin platinum wire to superheat the liquid and simultaneously stretched it using a plane acoustic wave; their study was limited to high temperature.…”

We report on measurements of the cavitation pressure in several liquids subjected to tension in an acoustic wave and compare the results to classical nucleation theory (CNT). This study is motivated by the sizable discrepancy between the acoustic cavitation threshold measured in water and the value predicted by CNT. We find that the same discrepancy is present for heavy water, whereas the agreement is better for ethanol and heptane and intermediate in the case of dimethyl sulfoxide. It is well-known that water is an anomalous liquid, a consequence of its hydrogen-bonded network. The other liquids studied represent very different molecular interactions. Our results indicate that the cavitation threshold approaches the prediction of CNT as the surface tension gets smaller. Conversely, this raises the question of the validity of a simple theory such as CNT to account for high surface tension liquids and suggests that an appropriate microscopic model of such liquids may be necessary to correctly predict the cavitation threshold.

“…Zengh et al [4] were able to experimentally reach about -150 MPa, a value believed to be very close to the maximal tension water can sustain [24,25]. A few other liquids have been investigated [30], such as ethanol, [20]. SB is the sublimation line (coincident with the Ã-axis in this large pressure scale).…”

Nature uses negative pressures in the most resourceful and efficient ways. Yet, negative pressure states are still sometimes considered inaccessible by part of the scientific community. In this paper we show that any condensed phase can exist in absolute negative pressure regimes, while the same is not true for gas phases. We also demonstrate that such states are not merely possible but have, in spite of their metastability, been observed experimentally on numerous occasions. Moreover, physical properties of several substances and mixtures have already been determined in the stretched liquid phase at absolute negative pressures. Nevertheless, conceiving of and succeeding in an experiment that produces high tension in a liquid are rather difficult. Thus, equations of state and computer simulations are powerful tools for studying metastable liquids. By using a simple equation of state we show: how negative pressure regimes can be attained; the maximum intrinsic tension a liquid can sustain; and below which temperature a liquid can be found in this state. Experimental and theoretical work on liquids at negative pressures is reviewed. Furthermore, the similarities and differences between negative temperature and negative pressure states are demonstrated. Due to water's non-trivial behavior as well as its technological and scientific importance, it has been the most studied substance in metastable phenomena. We will thus devote particular attention to some of the rich features of its metastable phase diagram. Water belongs to a class of substances that presents density anomalies. We also show how the negative pressure region of the phase diagram proves to be paramount in understanding the unusual behavior of this class of substances.

“…When a stainless steel tube, filled with water and then sealed with a softer metal plug (Cu or Ni), was repeatedly heated and then cooled over an appropriate temperature range (temperature cycle), the negative pressure at which cavitation occurred usually increased with the number of cycles, although it levelled off after many cycles. When the sealing metal was de-gassed beforehand, eventual negative pressures were found to be raised to -170 bar for water [3] and to around -200 bar for some organic liquids [4].…”

We inserted pieces of metal foils (AI and Au) into a metal Berthelot tube together with water or xylene to investigate whether corrosion of metals limits the achievement of negative pressure. For the test using AI foil with water, the negative pressure rose to -30 bar but diminished almost to zero after 250 cycles, whereas those for all the others increased with the number of temperature cycles.Corrosive reaction of AI with water yielded HP gas and the resulting increase in the
