Notes:
Several researches have been developed in order to verify the porosity effect over the ceramicmaterial properties. The starch consolidation casting (SCC) allows to obtain porous ceramics by usingstarch as a binder and pore forming element. This work is intended to describe the porous mathematicalbehavior and the mechanical resistance at different commercial starch concentration. Ceramic sampleswere made with alumina and potato and corn starches. The slips were prepared with 10 to 50 wt% ofstarch. The specimens were characterized by apparent density measurements and three-point flexural testassociated to Weibull statistics. Results indicated that the porosity showed a first-order exponentialequation e-x/c increasing in both kinds of starches, so it was confirmed that the alumina ceramic porosityis related to the kind of starch used
