Description

Key Advantages
Optimal Composition for Ionic Conductivity
The 10% scandia (Sc?O?) stabilization enhances zirconia??s cubic phase stability, while 1% ceria (CeO?) doping further improves oxygen ion mobility. This combination results in high ionic conductivity at intermediate temperatures (600-800??C), critical for efficient operation of SOFCs and oxygen separation membranes.
Fine Particle Size (0.2-0.5 ??m)
Small, uniform particle size promotes dense sintering at lower temperatures, reducing grain boundary resistance and enhancing mechanical strength in the final ceramic. This ensures consistent performance in high-temperature applications where structural integrity is paramount.
Exceptional Thermal Stability
Resists phase transformations (e.g., tetragonal-to-monoclinic) under thermal cycling, minimizing cracking or degradation in environments with rapid temperature changes??such as automotive exhaust sensors or industrial furnace components.
High Mechanical Strength
Sintered SSZ ceramics exhibit excellent hardness and fracture toughness, making them suitable for high-wear applications (e.g., thermal barrier coatings for gas turbines) or structural parts in extreme environments.
The technical specifications are as follows: Chemical Formula (Sc?O?)?.?(CeO?)?.??(ZrO?)?.??, Particle Size Range 0.2-0.5 ??m, Purity ??99.9%, Crystal Structure Cubic fluorite, Sintering Temperature 1300-1500 ??C, Bulk Density (Sintered) 6.0-6.2 g/cm3
Applications
Solid Oxide Fuel Cells (SOFCs)
Used as electrolyte materials in intermediate-temperature SOFCs, enabling efficient conversion of chemical energy to electricity with low emissions.
Oxygen Sensors
Powers high-precision sensors in automotive exhaust systems, industrial furnaces, and medical gas analyzers, leveraging high ionic conductivity for accurate oxygen concentration measurement.
High-Temperature Coatings
Applied as thermal barrier coatings (TBCs) on gas turbine blades or rocket components, protecting against extreme heat while maintaining structural integrity.
Ceramic Membranes
Used in oxygen separation membranes for industrial gas processing, enabling efficient extraction of pure oxygen from air.
Customization Options
Particle Size Tuning: Available in narrower ranges (e.g., 0.2-0.3 ??m) for specialized sintering requirements.
Doping Variations: Custom scandia/ceria ratios (e.g., 8% Sc?O? + 2% CeO?) to optimize conductivity for specific temperature ranges.
Surface Treatment: Optional surface modification (e.g., alumina coating) to enhance sintering behavior or reduce agglomeration.
