Effect of interconnecting pores

After compression and mercury intrusion during the extrusion cycle, some of the mercury is trapped in the porous structure. This is due to

Several experimental studies using transparent models indicate that intrusion is governed by the capillaiy resistance of the pore necks whereas mercury retention during extrusion is controlled by the capillary resistance of pore bodies [45-47]. 

Snap-off of threads of mercury, which results in mercury retention, has also been studied extensively [48,49].
