The principal drawbacks are related to the difficulties in obtaining high porosity and regular pore size.

Due to a higher porosity within the fracture, a greater amount of oil and natural gas is liberated.

Because of their high porosity, rudist reefs are highly favored oil traps.

Due to its higher porosity, it must usually be glazed in order to be watertight.

Their high porosity (of up to 30%) seems to be correlated to that fact.

CMCs obtained with this process usually have a high porosity of about 20%.

Their high porosity makes them also ideal in the production of activated carbon by pyrolysis.

Spent diatomaceous from the brewing process can be added to ceramic mass for the production of red bricks with higher open porosity.

In addition, the high porosity of the soil makes a fellfield a difficult place for plants to grow.

Bamboo charcoal is known to have high porosity.
