What is Cerium oxide?
Chemical properties
-100 mesh golden green with 99.9% purity; trig; can be prepared by heating powder(s) carbon and CeO2 at 1250°C in CO atmospheric [KIR78] [CER91]
The Uses of Cerium oxide
The compound cerium oxide (either Ce2O3 or CeO2) is used to coat the inside of ovens because it was discovered that food cannot stick to oven walls that are coated with cerium oxide.
