Alumina-zirconia composite powder were prepared from aluminium iso-propoxide, zirconium n-butoxide and various organic ligands which were 1,2-ethallediol, 1,2-propanediol and 1,3-propanediol. The effect of organic ligands on properties of the alumina-zirconia composite powder was investigated. It was suggested that the amount of organic compounds in the dry gels and the homogeneity of the alumina-zirconia composite powder changed with the species of organic ligand. The specific surface area, the pore volume and the pore size distribution of the alumina-zirconia composite powder depended on the organic ligand, and the pore size of the alumina-zirconia composite powder is distributed from 1 to 4 nm in radius. The control of pore size distribution by varying the kind of organic ligands was suggested.
