Abstract
An alumina body having nano-sized open-cell pores, the alumina body is formed from α-Al 2 O 3 and Al(OH) 3 . The alumina body has porosity of greater than 36-percent by volume and a mean pore flow diameter less than 25-nm. The alumina body retains porosity of over 20-volume percent for temperatures up to 1510° C. for 1-hour. The nano-sized open-cell porous body can be scaled to any 3-dimensional structure.
Claims (3)
1 . A ceramic body, comprising:
α-Al 2 O 3 having a porosity of greater than 36 percent by volume and a mean open pore flow diameter less than 25 nanometers.
2 . A ceramic body as recited in claim 1 , wherein said porosity stays above 20 percent by volume at an annealing temperature of 1510° C. for 1 hour.
