A-PLANE SAPPHIRE COLLOIDAL SILICA FEATURES

Sapphire Substrate is a kind of extremely hard semiconductor substrates, Kona engineering developed Sphere Substrate Polishing Slurry, including colloidal silica and alumina slurry.

Because of its good hardness and light transmittance, A-plane sapphire is widely used in various window materials, such as the transparent cover of watch and various medical Windows. Lapping and polishing processing to A-Plane sapphire is difficult, must choose the appropriate polishing slurry for polishing, otherwise it is really hard to polish the a-plane sapphire surface.
