Abstract
A novel fabrication process for porous alumina-based ceramics was developed using hydraulic inorganic binder (hydraulic alumina) and water. The hydraulic alumina and water acted as agents for direct consolidation, and water acted as a fugitive material to create open pores too. The green bodies formed with the hydraulic alumina and water had low green densities and high compressive strength. Hydraulic properties and sintering of the hydraulic alumina were studied.
