Q&A

1. What is rare earth polishing powder?

Rare earth polishing powder is a high-purity compound used for polishing optical components, semiconductor wafers, and delicate surfaces like glass and lenses. It delivers a smooth, high-clarity finish without damaging the material.

2. How do I choose the right rare earth polishing powder for my application?

To select the ideal polishing powder, consider factors like the material you’re polishing, the required finish, and specifications like particle size and purity. Our sales team is available to help you choose the perfect product for your needs.

3. How should I store  rare earth polishing powder?

Store in a cool, dry place, away from moisture and direct sunlight. Keep the powder in airtight containers to prevent contamination and maintain its effectiveness. With proper storage, it typically lasts 1-2 years.

4. Do you provide customized rare earth formulations?

Yes, we offer custom rare earth polishing powders and slurries, tailored to meet your specific needs, including adjustments to particle size, chemical composition, or slurry consistency.
