Product Description
Fine Grade Cerium Oxide Powder for Precision Optics Final Polishing
Product Overview
This fine grade cerium oxide powder is engineered as a high-performance rare earth abrasive for the final precision polishing stage of optical components. Controlled narrow particle size distribution combines mild chemical etching with micro mechanical abrasion to achieve sub-nanometer surface roughness. Widely used for finishing optical lenses, windows, prisms and infrared optical substrates.
Key Features
- Ultra-fine uniform particle size, minimal oversized particles
- Low micro-scratch performance for sensitive optical surfaces
- Balanced chemical activity for glass material removal
- Excellent suspension stability when formulated into polishing slurry
- Consistent batch quality for high-volume optical production
