Abstract: PROBLEM TO BE SOLVED: To obtain zirconium dioxide having high monoclinic system ratio end large BET surface area. SOLUTION: This zirconium dioxide is composed of at least 80 wt.% of monoclinic system and has a BET surface area of at least 100 m /g. The production method consists of a process for forming precipitates by mixing a zirconium salt aqueous solution with ammonia, and the drying and calcination of the resultant precipitates. In this process, the precipitates formed in the aqueous solution is aged at 0-300 deg.C and calcined at 200-600 deg.C, before drying. This product can be used as a formed product, a catalyst or a catalyst support.
