Al2O3 bodies possessing interconnected macropores through large-diameter connecting channels were prepared in this study using various Al2O3 powders and different templates. The Al2O3 powders used were 20I-Al2O3 powder, 1I-Al2O3 powder, and 0.8S-Al2O3 powder. Methyl cellulose (MC), activated carbon (AC), sodium bicarbonate (SC), granular carbon (GC, BGC), human hair (HH), and a shoe bruch (SB) were used as the templates. The average pore size of the Al2O3 body obtained from 20I-Al2O3 powder was below 50 μm, which was ca. 10 μm larger than that obtained from 1I-Al2O3 powder under otherwise identical experimental conditions. The templates [MC & AC], [MC & SC], and MC were inadequate for developing macropores in the Al2O3 body. On the other hand, the average pore size developed by [MC & GC] and [MC & BGC] was much larger than 50 μm. It was possible to prepare bodies having interconnected macropores through large diameter connecting channels when HH or SB was used together with [MC & GC] or [MC & BGC].
