Product Overview
This γ-phase aluminum oxide nanopowder represents a high-performance material engineered for demanding laboratory and industrial applications. With a minimum purity of 99%, this nanopowder exhibits exceptional thermal stability up to 1000°C while maintaining its crystalline structure. The γ-alumina form provides a unique combination of high surface area (typically 100-200 m²/g) and mesoporous structure, making it particularly effective for catalytic applications where surface interactions are critical. The uniform nanoparticle size distribution (typically 20-50nm) ensures consistent performance in composite materials and coating applications. Unlike conventional alumina forms, this γ-phase variant demonstrates superior resistance to phase transformation during high-temperature processing, preserving its desirable properties throughout extended use cycles. The material’s inherent chemical inertness combined with its high purity makes it suitable for sensitive applications where contamination must be minimized. When properly stored in sealed containers, this nanopowder maintains its reactive properties for extended periods without degradation.
FAQs
1. What distinguishes γ-phase alumina from other alumina forms?
γ-phase alumina maintains a defective spinel structure that provides higher surface area and catalytic activity compared to α-phase alumina, which has a more stable corundum structure but lower surface area.
2. How should this nanopowder be stored to maintain its properties?
Store in a tightly sealed container under dry conditions at room temperature, protected from moisture and direct sunlight to prevent agglomeration and maintain its reactive surface properties.
3. What particle size range can be expected with this γ-alumina nanopowder?
The primary particle size typically ranges between 20-50 nanometers, though some soft agglomeration may occur during storage which can be dispersed through mild sonication.
4. Is this material compatible with common organic solvents?
Yes, γ-alumina nanopowder can be dispersed in most polar and non-polar organic solvents, though dispersion quality may vary based on the specific solvent and any surface treatments applied.
5. What safety precautions should be taken when handling this nanopowder?
Use standard nanoparticle handling procedures including respiratory protection, gloves, and work in a well-ventilated area or fume hood to avoid inhalation of fine particles.
