Sapphire polishing slurry is a dedicated polishing suspension developed for single-crystal sapphire. It meets the polishing requirements of sapphire LED substrates, PSS patterned sapphire substrates, optical windows, infrared sapphire lenses, smart watch sapphire covers, camera protective lenses and other sapphire components.

We provide rough, medium and fine polishing grades. Abrasive options include nano silica, diamond, alumina and ceria. The slurry has stable material removal rate, well-dispersed abrasives and low agglomeration. It minimizes scratches and pits and controls surface roughness precisely. Compatible with CMP machines and surface grinders.
