Procedure

An aqueous cerium (III) nitrate solution was prepared by dissolving 58.6 g of cerium (III) carbonate (49.5 wt % oxide) in 135 g water and 50.4 g concentrated nitric acid. To this was added 110.5 g zirconyl nitrate (20 wt % oxide). The final mixed nitrate solution had a concentration of 15.7 wt % solids. 50 g of 30% an aqueous hydrogen peroxide was added to the nitrate solution. Into a heal of 350 g of 70° C. DI water, the peroxide treated nitrate solution was co-precipitated in a vessel against 300 ml 5N ammonia. A temperature of 70° C. and to maintain a pH of 8.6. After all of the solution has been added the precipitate was aged at 70° C. for 0.5 hours.
