Step-by-Step Guide: How to Use Cerium Oxide for Polishing Glass and Metals
Using cerium oxide for polishing is straightforward but requires proper technique:
- Prepare the Surface: Clean the glass or metal surface to remove dirt and debris.
- Mix the Powder: Combine cerium oxide powder with water to create a thin paste.
- Apply the Paste: Spread the paste evenly on the surface using a soft cloth or polishing wheel.
- Polish: Use a circular motion to gently remove scratches and imperfections.
- Clean the Surface: Rinse off excess powder and dry with a clean cloth.
For hand polishing, use a sponge or soft pad to avoid scratching delicate surfaces. For professional use, a high-grade polishing wheel can help achieve faster results.
Cerium Oxide vs. Zinc Oxide: A Comparative Overview
| Property | Cerium Oxide (CeO₂) | Zinc Oxide (ZnO) |
