Cerium is used in catalytic converters, glass polishing, alloys, and as a pigment for various products. Its primary application is in the automotive industry to reduce emissions, where its catalytic properties are key. It also enhances the precision of optical glass through polishing and improves the properties of alloys, including those used in aerospace. Additionally, cerium compounds serve as red pigments, replacing toxic cadmium, and are components in self-cleaning ovens and lighter flints. 
Here are some specific uses of cerium:

• Pigments:
  Cerium sulfide creates vibrant, stable red pigments, offering a safer, non-toxic alternative to cadmium-based pigments for toys, ceramics, and household items. 

• Fuel Additives:
  Mixed into fuel, cerium can improve engine performance and reduce fuel emissions. 

• Other Applications:
  • Flints: A component of Misch metal, used to make flints for cigarette and gas lighters. 
  • Ceramics: Used as a decolorizing agent and to make glass opaque to ultraviolet radiation. 
  • Self-Cleaning Ovens: Cerium oxide is part of the walls of self-cleaning ovens. 

• Catalytic Converters:
  Cerium oxide is a vital component in automotive catalytic converters, aiding in the reduction of harmful exhaust emissions. 
• Glass Polishing:
  It is widely used in the optics industry for fine polishing of glass and to make glass opaque to near-ultraviolet light. 
• Alloys:
  Cerium is a crucial alloying agent in various metals, including aluminum and steel, to enhance their strength, stability, and oxidation resistance.
