Lithium Niobate Crystal Polishing Colloidal Silica

Lithium niobate crystal because of its excellent piezoelectric, ferroelectric, electro-optical properties, is made into substrates for various electronic components and equipments, its similar products are lithium tantalate and lithium carbonate crystals, etc.

Both applications of these crystalline materials used in optical and electronic industries all require the formation of substrates, which require cutting, grinding and polishing.

Our alkaline Nano Colloidal Silica delivers a good removal rate and damage-free polishing for optical and electronic substrates polishing, such as Lithium Niobate.

LITHIUM NIOBATE CRYSTAL POLISHING SLURRY FEATURES

Kona Special Colloidal Silica has been developed for Crystal and electronic substrates polishing process, such as Lithium Niobate (LiNbO3), providing excellent surface finishes.

We also have developed lapping or fine polishing slurry for a wide variety of Crystal Materials.

Our Colloidal Silica delivers a good removal rate and damage-free polishing.

Our nano Colloidal Silica can reduce friction between polishing pad and Lithium Niobate (LiNbO3)workpiece, and helps to improve surface quality, has significant effect on surface roughness(Ra/Rz).

Alkaline PH as a factor to the colloidal silica to improve the polishing speed, also suitable for the chemical characteristics of Lithium Niobate(LiNbO3).

DETAILS OF LITHIUM NIOBATE CRYSTAL POLISHING SLURRY

Lithium niobate is a ferroelectric with the highest Curie temperature found so far. It is a negative crystal. This mechanism of lithium niobate and lithium tantalate makes them good piezoelectric energy exchangers and optical materials. The optical properties and research of lithium niobate crystals mainly focus on the visible and infrared bands.

Due to the high demand of its application, the surface of lithium niobate wafer often needs to undergo precise machining to obtain good surface characteristics.

For the final polishing process, Kona developed a nano precision polishing slurry based on silica abrasive, which provides the surface of lithium niobate wafer a good smoothness, finish and brightness.
