Large Surface Area CeO₂

[Applied Field]

• They can be used in petroleum decomposing and cracking, automobile exhaust controlling and catalyzing.

[Product Properties]

• The products are prepared by coprecipitation. They can keep large specific surface area under high temperature by adding stabilizing agents and controlling the agglomeration during the powder preparation process.
