Using urea as homogeneous precipitant, the precursor of mesoporous zirconia was synthesized by hydrothermal method. After heat-treatment at 500～550 ℃ for 2 h, the crystalline (t or m phase) mesoporous zirconia with short-range order was prepared. Their BJH desorption pore size and BET surface area are about 4～6 nm and 60～90 m2•g－1, respectively.
