I. Types and Applications of Mainstream Industrial Mirror Polishing Abrasives
1. Diamond Abrasives
Composed of synthetic diamond micropowder, diamond abrasives feature exceptional cutting force and superior stability, making them the optimal choice for mirror polishing of high-hardness materials. They are widely applicable to cemented carbide, silicon carbide, sapphire, and hardened steel. The abrasives efficiently remove surface scratches during rough polishing and deliver atomic-level mirror finishes in fine polishing processes. Primarily available in suspension and polishing paste forms, they are fully compatible with automated polishing equipment.
2. Alumina Abrasives
With cost-effective performance and moderate hardness, alpha-phase nano-alumina particles boast uniform particle size distribution, delivering outstanding fine polishing results for medium-hard materials. Suitable for stainless steel, aluminum alloy, copper alloy, and optical glass, these abrasives produce ultra-smooth surface finishes and are extensively adopted in precision hardware and mold mirror processing applications.
3. Silica Abrasives
Colloidal silica abrasives feature fine particle uniformity and excellent dispersion, with powerful synergistic chemical and mechanical polishing effects. They are the preferred option for low-damage polishing of soft and ultra-precision materials. Ideal for silicon wafers, gallium arsenide, soft metals, and optical lenses, these abrasives minimize surface micro-cracks and achieve ultra-flat mirror surfaces.
4. Cerium Oxide Abrasives
Integrating mechanical cutting capability and chemical activity, cerium oxide serves as a high-efficiency professional abrasive for glass and optical components. It is widely used for polishing mobile phone lenses, camera lenses, and optical glass, delivering significantly higher polishing efficiency than conventional abrasives and meeting the stringent requirements of high-precision optical mirror processing.
