Porosity, pore size and observed and calculated permeability ratio (%) for unidirectional porous ceramics prepared by freeze casting (Inline graphic [83], Inline graphic: [54], EF, Inline graphic: [70]), and conventional porous ceramics (▵: [84], ▿: [70], Inline graphic: [85]). The solid lines represent the permeability calculated using equation (2).
