The particle-stabilized foams method was successfully applied to fabricate the lightweight YSZ ceramic foams with closed pore structure and uniform pore size distribution. The microstructure of YSZ ceramic foams, including strut structure, porosity, mean pore size and pore size distribution were tailored by varying the sintering temperature, surfactant type and solid content of the initial slurries. When the sintering temperature at 1450 ℃ and solid content 32.50 vol%, YSZ ceramic foams with porosity of 83.7±0.2 %, mean pore size of 90.1±0.8 μm and compressive strength of 45.1±1.3 MPa were obtained through Isobam molecule and cationic surfactant dodecyl trimethyl ammonium chloride (DTAC) co-stabilized YSZ wet foam. The compressive strength of YSZ ceramic foams in present work was much higher than most reported results in the case of same porosity.
