Description

Cerium is a versatile rare earth metal with unique chemical properties that make it indispensable in advanced industrial applications. Its ability to readily change oxidation states underpins its role as a highly effective catalyst and polishing agent. This material is critical for manufacturers in the automotive, electronics, and glass industries seeking to enhance product performance and efficiency. Cerium CAS NO 13550-45-3 is supplied in various high-purity forms to meet stringent global manufacturing standards.

Application

• Catalyst Manufacturing: A key component in automotive catalytic converters for reducing harmful emissions and in fluid catalytic cracking (FCC) catalysts for petroleum refining.
• Glass & Polishing Compounds: Used as a polishing agent for precision optical lenses, semiconductor wafers, and flat-panel displays, and as a decolorizing and UV-absorbing agent in specialty glass.
• Metallurgy & Alloys: Employed as an alloying additive to improve the high-temperature strength, oxidation resistance, and workability of magnesium and aluminum alloys.
• Phosphors & Lighting: Serves as an activator in phosphors for LED lighting, fluorescent lamps, and X-ray intensifying screens.
• Ceramics & Pigments: Imparts specific yellow and orange hues in ceramic glazes and high-performance inorganic pigments.
• Chemical Synthesis: Acts as a potent oxidizing agent (ceric ammonium nitrate) and a catalyst in organic synthesis and polymerization reactions.
• Energy Storage: Investigated for use in components for solid oxide fuel cells (SOFCs) and advanced battery technologies.

Quality Control

Our Cerium is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and compliance with international standards. We provide comprehensive Certificates of Analysis (COA) detailing purity, metallic impurities, and physical specifications. Our quality protocols are designed to meet the exacting requirements of industries such as catalysis, metallurgy, and electronics, ensuring reliable performance in your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored in a cool, dry place under an inert atmosphere (e.g., argon) to prevent oxidation. The recommended storage temperature is 15-25°C. Keep away from strong acids and strong oxidizing agents.
