反応手順
A zirconium-cerium-lanthanum composite oxide (Powder A1) was obtained by hydrolyzing a zirconium oxychloride solution thereby obtaining zirconium hydroxide, adding an aqueous nitric acid solution of cerium and lanthanum to the zirconium hydroxide and mixing them together, neutralizing the resultant mixture by addition of an alkali, washing, drying at 120° C. for two hours and calcining at 700° C. for one hour the product of neutralization, with the relevant components used in amounts calculated to form a weight ratio of 40 g of zirconium oxide, 20 g of cerium oxide, and 15 g of lanthanum oxide.
