Cerium Oxide Polishing Powder
Chemical-mechanical polishing excellence
High-purity CeO₂ powder that combines mechanical abrasion with chemical surface modification — the definitive compound for mirror-finish edges on float glass.
How cerium oxide works
Four stages of chemical-mechanical polishing — from slurry preparation to mirror finish.
Slurry Preparation
Cerium oxide powder is mixed with water at 15–25% concentration. The slurry is agitated to ensure uniform particle distribution and prevent settling.
Why cerium oxide dominates
Four design advantages that make cerium oxide the industry standard for glass edge polishing.
Chemical-Mechanical Dual Action
Cerium ions exchange with silicon at the glass surface, producing a chemical polish that mechanical abrasion alone cannot achieve.
99.5% Purity Grade
Eliminates contaminants that cause haze, micro-scratching, or inconsistent finishes. Each batch is lab-tested for purity.
Neutral pH Formula
Safe for operators, equipment, and the environment. No special handling or ventilation required beyond standard dust protection.
Universal Compatibility
Works with all standard slurry delivery systems. Compatible with felt wheels, polishing pads, and cloth buffs across all major machine brands.
Technical details
High-purity cerium oxide powder that combines mechanical abrasion with chemical surface modification for superior mirror finishes on float glass.
Cerium oxide vs the alternatives
Head-to-head performance metrics against rouge and diamond polishing compounds.
Verdict
Cerium oxide wins on cost-effectiveness, removal speed, and universal compatibility. Diamond paste achieves finer surface quality but at 3–5× the cost. Rouge is legacy — cerium oxide outperforms it in every meaningful metric.
Optimized for every scenario
From high-throughput production lines to precision decorative work — cerium oxide adapts to your application.
High-Volume Float Glass
Architectural and construction glass production where throughput and cost-per-meter drive decisions. Cerium oxide delivers consistent mirror finishes at production speeds.

Keep your slurry performing
Five essential practices to maintain consistent polishing quality and extend material life.
Agitate Before Use
Cerium oxide settles in storage. Always mix the slurry thoroughly before starting production to ensure consistent particle distribution.
Monitor Concentration
Check slurry density regularly during production. Water evaporation increases concentration; add water to maintain the 15–25% range.
Filter Recirculated Slurry
If recirculating slurry, pass it through a 50μm filter to remove glass particles that cause surface scratching.
Store Sealed and Dry
Keep powder in original sealed containers. Moisture causes clumping that affects slurry consistency. Store below 30°C.
Clean Delivery Systems
Flush pumps and lines with clean water at end of each shift. Dried cerium oxide can block nozzles and cause uneven delivery.
