Abstract

<jats:p>Porous material was processed by the mixing, molding and pressing the ceramicmaterial, afterward burnout and sintering; through the forming porous, usingcorn flour at different concentration (10, 15 and 20 wt.%) as a pore formingagent; in order to determinate the influence of porous on the mechanical,morphological and structural properties. The effect of the volume fraction ofcorn flour in the mullite matrix, at various sintering temperature from 1100,1200, 1300 and 1500?C were tested by Diffraction X ray, showing changes incrystalline phases of mullite (3Al2O3-2SiO2), as result of sinteredtemperatures. Presence of talcum powder in formula, also cause the formationof the cordierite and cristobalite crystalline phases, giving stability andadhesion to the structure of ceramic material. When sintering at temperaturesbetween 1300 to 1500?C, and it was used the concentration of corn flour 15-20wt.% as forming agent porous, it was found the better mechanical properties.The scanning electron microscopy analysis shows the presence of open porosityand anisotropy.</jats:p>
