In this work concentrated alumina suspensions have been emulsified with decane using silica nanoparticles of a range of hydrophobicities as stabiliser giving rise to novel porous ceramic materials. The materials are characterized by open porosities between 49 and 61% and average cell sizes between 18 and 25 μm. Comparison with surfactant-stabilized emulsified suspensions is given. In particular, high temperature strength is a key property of the particle-stabilized materials.
