Overview

Description

The potassium-type silica sol product is prepared by elemental silicon hydrolysis, using KOH as a catalyst. The product has a uniform particle size and is a monodisperse system; the product has high purity, low impurity ion content, stabilizer is K+, and Na+ content is low, which can meet the needs of Na-sensitive industries; products within the particle size range of 10-100nm can be prepared. The particle size increases, and the appearance of the product transitions from slightly blue and transparent to milky white. Potassium-type silica sol is suitable for chemical mechanical polishing of various materials such as coatings and coatings.

Features
