The powder’s uniform particle size distribution guarantees reproducible results across experiments. Packaged in airtight containers to prevent oxidation, this zinc powder maintains its reactivity over extended storage periods. The material’s high density and metallic properties make it ideal for applications requiring controlled metal deposition or as a reducing agent in organic synthesis. Each batch undergoes rigorous quality control to verify purity and particle size consistency, ensuring reliable performance in critical laboratory procedures.

FAQs

1. What is the typical particle size distribution for this zinc powder?

The -140+325 mesh specification indicates particles pass through a 140-mesh screen (106 microns) but are retained on a 325-mesh screen (45 microns), providing a controlled size range for consistent reactivity.

2. How does the 99.9% purity level affect performance compared to lower grades?

Higher purity reduces the presence of trace metals and oxides that could interfere with reactions, ensuring more predictable outcomes in sensitive applications like catalytic processes or electrochemical studies.

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

Use in a fume hood with proper ventilation, as fine metal powders can be pyrophoric. Wear gloves and eye protection to avoid skin contact or inhalation of dust particles.

4. Can this zinc powder be used for electrochemical applications?

Yes, the high purity and fine particle size make it suitable for battery research and other electrochemical applications where consistent metal deposition is required.

5. What is the recommended storage method to maintain purity?

Store in a cool, dry place in the original sealed container. Exposure to moisture can lead to oxidation, which may alter the powder’s chemical properties over time.
