The Strange–Rahman–Smith equation is used in the cryoporometry method of measuring porosity. NMR cryoporometry [1] [2] [3] is a recent technique for measuring total porosity and pore size distributions. NMRC is based on two equations: the Gibbs–Thomson equation, which maps the melting point depression to pore size, and the Strange–Rahman–Smith equation, [1] which maps the melted signal amplitude at a particular temperature to pore volume.
If the pores of the porous material are filled with a liquid, then the incremental volume of the pores with pore diameter between and may be obtained from the increase in melted liquid volume for an increase of temperature between and by: [1]
Where: is the Gibbs–Thomson coefficient for the liquid in the pores.
