Description

Praseodymium Doped Ceria (CeO2:Pr) is a high-performance, advanced ceramic material engineered for its exceptional ionic conductivity and catalytic properties. This compound is critical for applications requiring efficient oxygen ion transport and redox activity at elevated temperatures. It is primarily utilized by manufacturers and researchers in the solid oxide fuel cell (SOFC), sensor technology, and automotive exhaust catalysis sectors seeking to enhance energy conversion efficiency and environmental performance.

Application

• Solid Oxide Fuel Cell (SOFC) Electrolytes: Key component for intermediate-temperature SOFCs due to its high ionic conductivity and stability.
• Automotive Three-Way Catalysts (TWCs): Used as an oxygen storage component (OSC) in catalytic converters to reduce NOx, CO, and hydrocarbon emissions.
• Chemical Looping Combustion (CLC): Serves as an oxygen carrier material for cleaner fossil fuel combustion with inherent CO2 separation.
• Gas Sensors: Employed in oxygen and combustible gas sensors for industrial monitoring and control systems.
• Solar Thermochemical Water Splitting (STWS): Acts as a redox-active material for producing hydrogen from water using concentrated solar energy.
• Catalytic Oxidation Processes: Facilitates oxidation reactions in fine chemical synthesis and pollution abatement technologies.
• Protective Coatings: Applied as a thermal barrier coating (TBC) or corrosion-resistant layer on high-temperature alloy components.

Quality Control

Our Praseodymium Doped Ceria is manufactured under controlled conditions and undergoes rigorous quality testing to ensure batch-to-batch consistency and performance. Key parameters such as phase purity, dopant concentration, particle size distribution, and specific surface area are strictly monitored. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed in a dry environment to prevent absorption of atmospheric moisture and CO2, which can affect performance.
