Description

Yttrium Stabilized Zirconium Oxide is a high-performance ceramic material renowned for its exceptional thermal stability, mechanical strength, and ionic conductivity. This engineered compound is critical for applications requiring durability under extreme thermal and mechanical stress. It is an essential material for manufacturers in the advanced ceramics, electronics, and thermal barrier coating industries seeking reliable, high-purity components.

Application

• Solid Oxide Fuel Cells (SOFCs): Used as a key electrolyte material due to its high oxygen ion conductivity at elevated temperatures.
• Thermal Barrier Coatings (TBCs): Applied to gas turbine engine components (e.g., blades, vanes) to provide insulation against extreme heat and improve engine efficiency.
• Advanced Structural Ceramics: Manufactured into components for industrial wear parts, cutting tools, and biomedical implants (e.g., dental crowns, hip joint heads) for its high fracture toughness and biocompatibility.
• Oxygen Sensors: Serves as the sensing element in lambda sensors for automotive and industrial exhaust systems to monitor oxygen concentration.
• Catalyst Supports: Provides a stable, high-surface-area substrate for various catalytic processes in the chemical industry.
• Electronic Ceramics: Used in capacitors, piezoelectric devices, and other electronic components for its dielectric properties.
• Abrasive and Polishing Materials: Utilized in precision polishing slurries for semiconductors, optical glasses, and hard surfaces.
• High-Temperature Furnace Linings: Employed as refractory materials due to its excellent resistance to thermal shock and corrosion.

Quality Control

Our Yttrium Stabilized Zirconium Oxide is produced under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters including phase composition (tetragonal/cubic), yttria content, particle size distribution, and specific surface area to ensure consistent performance for demanding technical applications. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent moisture absorption, which can affect flow properties and sintering behavior.
