How does the 500 nm particle size and 5-15 m2/g specific surface area of this alpha-phase alumina powder influence its sintering behavior compared to finer or coarser grades?
The 500 nm particle size and moderate specific surface area (5-15 m2/g) provide a balance between reactivity and packing density for ceramic sintering. The alpha phase ensures thermal stability, while the 99.99% purity minimizes unwanted grain boundary phases. This combination supports dense, high-quality ceramic bodies with controlled shrinkage.
Is this 99.99% alpha alumina powder suitable as a filler in high-temperature polymer composites?
Yes, the product is explicitly intended for use in plastics and rubber. Its alpha crystal phase provides thermal stability, and the 99.99% purity reduces catalytic degradation effects. However, the 500 nm particle size may require surface functionalization or coupling agents to ensure uniform dispersion in polymer matrices.
What are the recommended storage conditions to maintain the 99.99% purity and prevent moisture uptake of this aluminum oxide nanopowder?
Store in a sealed, dry container at room temperature in a low-humidity environment to prevent moisture adsorption. The high specific surface area (5-15 m2/g) makes it susceptible to water vapor. Avoid exposure to acidic or alkaline atmospheres to maintain purity. Detailed storage recommendations are provided in the SDS available upon request.
Atomfair Alpha Nano Aluminum Oxide Powder with 99.99% purity and 500 nm particle size is evaluated for use in ceramics, plastics, and rubber research. The alpha phase provides thermal stability, while the 5-15 m2/g surface area range and documentation require attention for reproducible results.
Positive
- High purity grade for research: 99.99% purity eliminates common contaminants, enabling reliable baseline data in advanced ceramics, plastics, and rubber studies.
- Defined alpha crystal phase: The alpha phase ensures consistent thermal and mechanical properties, critical for high-temperature processing and end-use performance.
Trade-offs
- Broad specific surface area range: The 5-15 m2/g range introduces batch-to-batch variability, requiring careful control for surface-area-sensitive applications.
- Documentation requires separate request: COA and SDS are not automatically included; batch-specific confirmation must be explicitly requested, adding a procedural step for procurement.
