FAQs

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

The product maintains a particle size distribution where 90% of particles are below 10 microns, with a median particle size typically around 5-7 microns, ensuring consistent performance in applications requiring fine powders.

2. How does the 99.99% purity compare to standard commercial grades?

This trace metal basis grade contains significantly fewer metallic impurities than standard commercial grades (typically 97-99%), with most metal contaminants reduced to parts-per-million levels, making it suitable for sensitive analytical applications.

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

Due to its fine particle size, use in a fume hood or with proper respiratory protection to avoid inhalation, and employ anti-static measures as the powder can become electrostatically charged during handling.

4. Can this product be used for luminescence applications?

While primarily designed for general laboratory use, the high purity makes it potentially suitable for luminescence applications, though specific doping requirements would need to be evaluated for optimal performance.

5. What is the shelf life of this zinc sulfide powder when stored properly?

When kept in its original sealed container at room temperature and protected from moisture, the product maintains its specified purity and properties for at least 24 months from the date of manufacture.
