Lithium niobate diamond abrasive liquid

Our company has a mature product layout and technology accumulation in the field of grinding and polishing of sapphire substrate materials, silicon carbide substrate materials, and single crystal silicon substrate materials, which can achieve rapid flattening of various substrate materials, while meeting customers’ basic surface requirements such as TTV, LTV, and Warp, improving processing efficiency, extending service life, and reducing costs and increasing efficiency through material and process improvements.

Introduction:

This diamond abrasive liquid is a high-performance polishing solution specifically designed for lithium niobate (LiNbO₃) crystal processing. The formulation incorporates precisely graded diamond particles in a stabilized colloidal suspension, combined with specialized chemical additives that enhance polishing efficiency while preserving crystal integrity. The solution delivers superior surface quality with controlled removal rates, achieving nanometer-level roughness essential for optoelectronic applications.

Application:

The liquid is primarily used in precision optics and photonics industries for manufacturing optical waveguides, piezoelectric devices, and electro-optic modulators. It enables efficient processing of lithium niobate components for telecommunications equipment, laser systems, and quantum technology applications where exceptional surface finish and edge definition are critical. The solution is compatible with both manual and automated polishing systems for various production scales.
