What is the significance of the 5 mol% Y2O3 content and tetragonal phase in this yttria-stabilized zirconia powder for oxygen sensor applications?
The 5 mol% Y2O3 content stabilizes the tetragonal phase at room temperature, which is critical for oxygen sensor performance because tetragonal zirconia exhibits high ionic conductivity. This specific stabilization enables reliable oxygen ion transport in sensor electrolytes. The product's defined crystal phase and Y2O3 content are specified to ensure consistent electrochemical behavior.
How does the specific surface area of 15-25 m2/g affect the processing of this powder for structural ceramics?
The specific surface area range of 15-25 m2/g indicates a moderate surface activity suitable for ceramic processing. Higher surface area can enhance sintering kinetics but may also increase agglomeration; this controlled range balances reactivity and handleability. For structural ceramics, this surface area supports uniform densification during sintering while maintaining manageable powder flow.
What documentation is available to verify the batch-specific purity and particle size for research use?
A Certificate of Analysis (COA) and Safety Data Sheet (SDS) can be provided upon request for batch-specific confirmation. These documents detail the actual purity (91.5%), particle size (30nm), and other parameters for the specific lot, ensuring traceability for research and procurement review.
Atomfair Yttria-Stabilized Zirconia Powder (30 nm, 91.5% purity, tetragonal phase) provides a controlled particle size and phase for structural and functional ceramic research, but the moderate purity level and nanoparticle handling requirements should be considered for high-sensitivity applications.
Positive
- Controlled 30 nm particle size: The specified 30 nm particle size enables uniform sintering behavior and consistent microstructure in nanoceramic processing, which is critical for reproducible mechanical and electrical properties.
- Defined tetragonal crystal phase: The tetragonal phase of Y2O3-stabilized ZrO2 offers high fracture toughness and oxygen ion conductivity, making it suitable for oxygen sensors and advanced structural ceramics.
Trade-offs
- Moderate purity level (91.5%): The 91.5% purity may introduce trace impurities that could compromise performance in ultra-high-vacuum or electrochemical applications requiring strict stoichiometry control.
- Nanoparticle handling requirements: The 30 nm particle size poses risks of dust inhalation and agglomeration; proper fume hoods and dispersion techniques are recommended during handling and processing.
