Abstract

The phase equilibria of water within porous silica has been studied by proton and deuteron magnetic resonance, Proton signal amplitude as a function of filling factor was measured, These protons arise from the proton-deuterium equilibrium that is established between the liquid and the absorbed layer on the pore wall, The results for temperatures below 0 degrees C show a maximum as a function of filling factor, theta. This suggests that the pores fill from either a surface layer or from the crevices and interstices into the center. Another experiment used cryoporometry to study the size of crystals formed within the pores as a function of theta and leads to the same conclusion. Copyright (C) 1996 Elsevier Science Inc.
