Properties of porous alumina ceramics

Author(s): Zaw Ye Maw Oo

Porous materials are commonly used as catalyst supports in the processes of oxidation, hydrogenation, and dehydrogenation at high temperatures, corrosion in feed processing- corrosive environments at endothermic and exothermic reactions. In particular, for this purpose, various types of corundum materials with high chemical inertness is needed. Porosity materials due to the high porosity and the peculiar structure have specific properties dramatically different from those of the corresponding chemical composition of dense materials. Then a highly porous cellular material of alumina carriers for catalysts was obtained. The filler used to be electro corundum, as reinforcing filler, forming on fire a bundle used porcelain. The samples were prepared by impregnating the ceramic slurry polyurethane foam (PUF), followed by drying and calcining at 1450 °C. The porosity after firing was 60-65%, compressive strength of 3.5 MPa.
