The oxide, mixed oxide and the solid solution and production manner null of cerium and the zirconium where thermal stability for the catalytic converter reaction of exhaust air gas system improves

摘要

(57) Abstract The mixed oxide and the solid solution, and cerium oxide of cerium and the zirconium where thermal stability improves are produced. This manner, makes the oxide, mixed oxide and the solid solution of cerium and zirconium with the manner such as the co-thermohydrolysis and coprecipitation, continuously the carbon atom to alkoxyl it is more than as many as 2 cleans with the chemical compound which is converted and or needs that impregnation it does this chemical compound. After the cleaning or impregnation process, calcining the blend, it makes the oxide which possesses with the very big surface area and oxygen storage capacity. Although those you use with the application like the catalytic converter, it makes the thermal stability where these oxides improve, profitable.
