Product Overview

This 99.5% pure aluminum powder (-325 mesh) is engineered for precision laboratory applications requiring high reactivity and consistent particle size distribution. The ultra-fine powder form ensures rapid dissolution and uniform mixing in chemical reactions, while the 99.5% metals basis purity minimizes impurities that could affect experimental outcomes. The -325 mesh classification guarantees particles pass through a 44-micron sieve, providing optimal surface area for catalytic reactions and thermal applications. The powder’s high surface-to-volume ratio enhances its performance in exothermic reactions, making it particularly valuable in specialized formulations. Each batch undergoes rigorous quality control to maintain consistent particle morphology and chemical composition. The material is packaged in airtight containers to prevent oxidation and moisture absorption during storage. This grade of aluminum powder meets the stringent requirements of advanced research applications where material consistency and purity are critical factors.

FAQs

1. What is the particle size distribution range for this -325 mesh aluminum powder?

The -325 mesh designation means all particles pass through a 44-micron sieve, with the majority of particles typically ranging between 10-44 microns in diameter.

2. How does the 99.5% purity compare to standard commercial grades?

This 99.5% metals basis purity exceeds most commercial grades (typically 98-99%) by reducing trace impurities like iron, silicon, and copper that could interfere with sensitive reactions.

3. What precautions should be taken when handling this fine aluminum powder?

Use in a well-ventilated area with proper dust collection, as the fine particles can create explosive mixtures in air. Ground all equipment to prevent static discharge.

4. Is this powder suitable for creating aluminum thermite mixtures?

Yes, the high purity and fine particle size make it ideal for thermite formulations, though exact ratios should be calculated based on your specific reaction requirements.

5. How should this powder be stored to maintain its properties?

Store in the original airtight container at room temperature, away from moisture and oxidizing agents. For long-term storage, consider adding desiccant packets to the container.
