3.1 Interpretation of results
Before using the data to calculate textural characteristics, the curves obtained must be analyzed to determine in which pressure and volume domains calculations based on the Laplace-Washburn equation are possible. An example of a typical result on a porous silica sample with an average particle size of 15 μm is shown in figure 7 . Several ranges can be distinguished on these intrusion-extrusion curves, which are characteristic of a powder sample. Between 0 and 0.04 MPa, pressure increases steadily without any...
