摘要：

Two ceramic systems in a flat sheet configuration have been prepared. These systems will be used for deposition of mesoporous membranes with a high porosity volume, therefore the quality of these supports must be also very high. These systems consist of a support and a different number of intermediate layers deposited on it. Two different system have been prepared and compared. The supports are obtained by pressing and the intermediate layers will be deposited by dipping. Rheological studies have been carried out to adjust the viscosity of the suspensions. Mercury porosimetry, permeability measurements and microscopic characterization are used to evaluate the quality of the intermediate layers and the final membrane system.
