Understanding Cerium Oxide Polishing Fundamentals

Cerium oxide (CeO₂) has become the gold standard for precision polishing due to its unique chemical-mechanical action. Unlike conventional abrasives, cerium oxide particles exhibit a self-sharpening characteristic where fractured particles reveal fresh cutting edges during the polishing process. This property makes it exceptionally effective for achieving sub-nanometer surface roughness on materials like:

Particle Size Distribution Matters

XYT's proprietary grading technology ensures cerium oxide particles maintain:

Grade Particle Size (µm) Applications
Coarse 3.0-5.0 Rapid material removal
Medium 1.0-3.0 Intermediate polishing
Fine 0.5-1.0 Final finishing

Advanced Cerium Oxide Polishing Techniques

Robotic Polishing Systems

Modern automated systems integrate XYT's cerium oxide abrasives with 6-axis robots for:

  • ±0.01mm positioning accuracy
  • Consistent pressure control (20-200kPa)
  • Real-time surface monitoring

Dual-Action Polishing (DAP)

Our patented DAP method combines rotational and orbital motion to eliminate directional scratch patterns, achieving Ra values below 0.5nm on BK7 glass.

Industry-Specific Applications

Fiber Optic Communications

XYT's cerium oxide solutions meet Telcordia GR-326-CORE standards for:

  1. Insertion loss <0.2dB
  2. Return loss >55dB (PC), >65dB (APC)
  3. Ferrule endface radius curvature 10-25mm
