Procedure

A cerium (III) nitrate solution was prepared by dissolving 58 g of cerium carbonate in 135 g water and 43 g concentrated nitric acid. To this was added 107.7 g zirconyl nitrate (20 wt % oxide) and 3.5 g lanthanum nitrate to yield 2 wt % La2O3 in final product. No hydrogen peroxide was added. The nitrates were coprecipitated as in Example 1. The surface area of the powder after aging at 900° C. for 4 hours was 20 m2/g.
