Zirconia toughened alumina (ZTA) is one of the leading engineering ceramics; it is used in a wide range of components and products in applications for which high strength, high toughness, and high temperature stability are needed. The particle-stabilized direct foaming method has lately become a subject of particular interest. Nevertheless only a few studies on combining ZTA ceramics and particle-stabilized direct foaming have been reported. Therefore, in this study, ultra-low density ZTA foams having single strut wall thickness, cell size ranging from 80 μm to 200 μm, and above 90% porosity were successfully fabricated via the particle-stabilized direct foaming method. Valeric acid was used as particle surface modifier to render the particles partially hydrophobic, which stabilized the air/water interface of the ZTA foams. The sintered foams maintained compressive strength up to 8 MPa with porosity of 90%.
