Manjunatha Pattabi· Mangalore universityMarcello Romagnoli· Università degli Studi di Modena e Reggio EmiliaMy suggestion is the following.

We can assume that the area of contact is equal to:

Contact area = Surface area - Area of the pores

Surface area = Total area of the particles not in contact

Area of the pores = Area of the pores when the particles are in contact

The first one can be measured by BET, the second one can be estimate by measure of porosity using the mercury method.

Both the measures have an interval of error so the results are not perfectly correct.
