Evaluation of interparticle pore network of porous carbon material using macro crystal model
Capillary rise of cyclohexane and water on graphite powder was measured in order to evaluate the interparticle pore network. The reduced diameter (d*) of the pore network was determined from the sorbed height of cyclohexane using Young-Laplace equation. The effectiveness of the d* value was examined by calculation of the contact angle of water on graphite powder surface from the sorbed height of water. It was clear that d* has serious relationship with the average pore width of this macro crystal model. Though we have a possibility to adopt the idea of d* on micropore system, the real meaning of d* is still not clear.
