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.
- Excellente stabilité thermique : 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.
- Inertie chimique : 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.
- Capteurs d'oxygène : 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.
