Product Details

Basic information

Cerium oxide appears as a light yellow powdery substance. It is not soluble in water or alkaline solutions, and shows only limited solubility in acidic media. This compound finds extensive application across multiple industries, including precision polishing, catalytic processes, and as a support material or additive in catalysts. It also serves as an effective UV absorber, plays a role in solid oxide fuel cells as an electrolyte component, aids in treating automotive exhaust, and is utilized in the production of advanced electronic ceramics.

Application

1. Glass Polishing

Glass Polishing: It is the most widely used application. Cerium oxide is the primary component in polishing powders used for fine grinding and polishing of optical lenses, mirrors, camera lenses, semiconductor wafers, and LCD screens.

2. Glass and Ceramics

Glass Decolorizer: Cerium oxide is added to glass to remove the greenish tint caused by iron impurities, making the glass clearer.

UV Protection: It is added to glass to absorb ultraviolet (UV) light, used in automotive glass, eyewear, and specialty containers to protect contents from UV damage.

Ceramic Glazes: Used as an opacifier and pigment in ceramic glazes to produce white or yellow hues.

3. Other Specialized Uses

Semiconductor Manufacturing: Used for Chemical Mechanical Planarization (CMP) to polish silicon wafers.

Sensors: Utilized in oxygen sensors for monitoring exhaust systems due to its ability to store and release oxygen.

LED Lights: Used to suppress the yellowing of LED encapsulating materials.
