Abstract Monitoring the pore structure is one of the most challenging objective in order to achieve optimal material properties in porous functional structures. The pore size obtained by stacking the particles followed by sintering is primarily affected by particle size and particle size distribution of the starting powder. Thorough slip preparation is a prerequisite in order to obtain controlled microstructure in the sintered body formed by aqueous slip casting. Furthermore, an important parameter affecting the pore geometry in the fired structures is the sintering temperature. In the present study the structure of porous layers have been analyzed after being sintered at different temperatures. Used parameters have been apparent porosity and dynamic mean pore diameter. The mean pore diameters have been determined based on two different techniques i.e. liquid-expulsion method and wicking technique, which show systematic differences in the detected limiting dynamic pore sizes.
