Ceria (Cerium Oxide, CeO2)
Ceria is an oxide-based engineering ceramic. It has a very high density and a fairly low heat capacity among oxide-based engineering ceramics. The graph bars on the material properties cards below compare ceria to other oxide-based engineering ceramics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
