POROUS ALUMINUM TITANATE, SINTERED BODY OF THE SAME, AND METHOD FOR PRODUCING THE SAME

摘要

To obtain novel porous aluminum titanate in which aluminum titanate itself is porous, a sintered body of the porous aluminum titanate and a method for producing the porous aluminum titanate. Porous aluminum titanate is composed of porous particles having a form in which a plurality of particles of amoeba-like shape having a plurality of projections extending in random directions are fused together. For example, its pore volume within the pore diameter range of 0.0036 to 10 µm in a pore size distribution as measured by a mercury porosimeter is 0.05 ml/g or more.
