Abstract Recently it was discovered that helium in confined geometries remains a liquid at pressures considerably above bulk melting. By combining a special technique for measuring pressures in small pores with thermal measurements, the phase diagram has been obtained for freezing and melting of4He in Vycor glass. The measurements cover the range of temperature from 0.8 to 2.5 K and extend to pressures of 6.0 MPa. At 1 K,4He is found to remain a liquid up to 4.2 MPa. The change in volume and latent heat on freezing are found and a complete analysis is given of the thermodynamics of freezing of helium in the Vycor.
