Introduction:

This lithium niobate polishing liquid is an advanced chemical-mechanical planarization solution specifically engineered for high-precision processing of LiNbO₃ crystals. The optimized formulation combines colloidal silica abrasives with specialized chemical additives to achieve atomic-level surface smoothness while maintaining excellent material removal rate control. The solution effectively minimizes surface defects and subsurface damage, critical for maintaining the unique piezoelectric and optical properties of lithium niobate substrates.

Application:

Essential for photonics and telecommunications industries, the liquid is widely used in manufacturing optical modulators, surface acoustic wave (SAW) devices, and nonlinear optical components. It enables high-quality finishing of lithium niobate wafers for 5G filters, fiber optic systems, and quantum computing applications where precise crystal orientation and surface perfection are paramount. The solution supports both laboratory-scale and industrial production requirements.
