Process

How cerium oxide works

Four stages of chemical-mechanical polishing — from slurry preparation to mirror finish.

Step 1

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.

Advantages

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.

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.

Applications

Optimized for every scenario

From high-throughput production lines to precision decorative work — cerium oxide adapts to your application.

Maintenance

Keep your slurry performing

Five essential practices to maintain consistent polishing quality and extend material life.

Tip 1

Agitate Before Use

Cerium oxide settles in storage. Always mix the slurry thoroughly before starting production to ensure consistent particle distribution.

Tip 2

Monitor Concentration

Check slurry density regularly during production. Water evaporation increases concentration; add water to maintain the 15–25% range.

Tip 3

Filter Recirculated Slurry

If recirculating slurry, pass it through a 50μm filter to remove glass particles that cause surface scratching.

Tip 4

Store Sealed and Dry

Keep powder in original sealed containers. Moisture causes clumping that affects slurry consistency. Store below 30°C.

Tip 5

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.
