Yttria Stabilized Zirconia Micropowder Description

Yttria Stabilized Zirconia Micropowder exhibits excellent resistance to thermal shock, chemical corrosion, and phase transformation, making it a high-performance material for use in harsh thermal and mechanical environments. It is widely applied in electrolyte layers of solid oxide fuel cells, thermal barrier coatings for jet engines, and high-strength structural ceramics. The stabilized cubic phase ensures long-term stability, while the fine powder form promotes uniform sintering and dense ceramic microstructures.

Yttria Stabilized Zirconia Micropowder Features

• High Ionic Conductivity: Enables efficient oxygen ion transport in solid oxide fuel cells, improving energy conversion efficiency.
• Excellent Thermal Stability: Maintains cubic or tetragonal phase up to 1500°C, with strong resistance to phase transformation.
• Superior Fracture Toughness: Enhanced mechanical durability compared to unstabilized zirconia, suitable for structural ceramic use.
• Fine and Uniform Particle Size: Offers excellent dispersibility and sintering behavior, producing dense and homogenous ceramic parts.
• Chemical Inertness: Resists corrosion and reaction with most acids, alkalis, and molten metals, allowing use in harsh chemical environments.

Yttria Stabilized Zirconia Micropowder Applications

• Solid Oxide Fuel Cells (SOFCs): Used as the electrolyte or functional layers due to their high oxygen ion conductivity.
• Thermal Barrier Coatings (TBCs): Applied on turbine blades and engines to withstand extreme temperatures.
• Oxygen Sensors: Serve as a key component in automotive and industrial gas sensors.
• Medical Ceramics: Applied in dental implants and joint prostheses for their toughness and biocompatibility.
• Advanced Refractories and Crucibles: Used in high-temperature processing of metals and glass.

Yttria Stabilized Zirconia Micropowder Packaging

The yttria stabilized zirconia micropowder is typically packaged in sealed, moisture-proof plastic bags, then placed in sturdy drum containers or fiber cartons to prevent contamination and ensure safe transport. Standard packaging sizes include 1 kg, 5 kg, and 10 kg options, with custom packaging available upon request to meet specific usage or storage needs.
