摘要：

A porous alumina with parallel channels has been prepared by combining a foaming method and sol-get technology. Samples were calcined at 800 degreesC, 1000 degreesC and 1200 degreesC, respectively. The volume shrinkage and compressive strength increased with calcination temperature. The porous alumina exhibited a bimodal pore structure when calcined below 1200 degreesC. The formation mechanism for porous alumina with parallel channels is discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
